Description

The device relates to the field of energy saving and can be used to adjust the illumination of lamps in the lighting line and maintain this voltage within certain limits, as well as stabilize the power of street and industrial lighting fixtures.

The following technical solutions are known from the prior art:

- Dimmer-stabilizer "Iluest +" (http://www.per-svstems.ru/statya_iluset), which is a control system for any lighting lighting networks. The device combines a digital control system and circuitry. As an electronic key in the circuit, triacs controlled by a microprocessor are used. The processor controls the transition of voltage through zero. An algorithm is stored in the volatile memory of the microprocessor that allows the operator to program the change in voltage over time, as well as to automatically correct the power of consumers according to the established profiles.

The disadvantage of this device is: lack of reliability, as in this device there is one microprocessor that “controls” the trips of the triac windings and fulfills predefined control algorithms.

- Utility model "IP-dimmer" (RU 80295, published January 27, 2009), the field of application of the utility model is automation, in particular, the lighting control system over a local area network - Ethernet. An IP dimmer containing an Ethernet module provides the most comprehensive lighting control over an Ethernet local area network. The technical result is the expansion of the functionality of the Ethernet LAN for lighting control through the use of new capabilities of the hardware and software parts of the device. This is achieved by the fact that a block of triacs is introduced into the device, one for each load channel, a synchronization block, a network filter, a connector for connecting the load.

The disadvantages of the utility model are: the inability to control street lamps such as DRL and DNAT.

- The closest technical solution is the patent "Light dimmer for Gas Discharge" (MX 2013002343, publ. 07.11.2013). A light dimmer for gas discharge lamps is described, which performs a gradual change in the voltage supplied to this type of lamp having transformer windings with a voltage proportional to the percentage of attenuation, which can partially be reduced when switching with a saturated core.

The disadvantages of the invention is that one of the components of this device is the electromechanical part, which is unreliable due to wear during operation and will require maintenance and repair costs.

The objective of the proposed utility model is to control the voltage of street lighting installations, to eliminate energy overruns and increase the lamp life, without replacing equipment (lamps, wires).

The problem is solved by using a voltage stabilization and adjustment device located between the transformer substation that feeds the lighting installations, and the lighting line itself with lighting installations, which allows, by smoothly regulating and stabilizing the alternating voltage in the lighting installations, to reduce energy consumption when using high-pressure discharge lamps and significantly increase their service life, as well as by switching input and output autotransformer windings with triac keys. Switching occurs in automatic mode, depending on the magnitude of the input voltage and the specified output voltage. Electricity consumption is reduced due to the initial stabilization of the overvoltage of the supply transformer substation and the forced reduction of the supply voltage.

The essence of the claimed utility model is that power triac keys are connected to the four input and four output windings of the autotransformer (not shown in the drawing). Through a certain inclusion of triac keys, three operating modes are implemented: norm, saving, minimum. It is possible to automatically switch the device to the desired mode. In addition, in the upper part of the Helios-Dimmer voltage stabilization and adjustment device, there are switches that are responsible for the additional bypass mode, which allows them to completely disconnect the device’s power circuits, which are responsible for saving modes, and switch the load power from the input voltage, when switching them. so that the device remains operational in case of breakdown of the autotransformer, power triac keys and microcontroller control.

The increase in the life of lighting devices is carried out due to the algorithms embedded in the device and providing a smooth kindling of lamps at normal voltage, and then reducing the value of the supply voltage according to the settings. Thus, the lamps operate in a gentle mode and their service life is increased by 20-25%.

At night, the supply voltage can be significantly higher than the rated voltage. Stabilization of the supply voltage at this time allows to reduce cases of equipment failure by 40%.

The voltage stabilization characteristics (burning level) are controlled both in manual mode (directly on the device) and as part of an automated control system (remote via GSM / GPRS, Enthernet channels and other digital communication channels from the control center), by executing microcontrollers that specify signals from manual control switches or from the control unit of the entire device.

Self-diagnosis of the power parts of the device is carried out by means of microcontrollers installed in these power parts, and ensures the normal functioning of the lighting system.

The device is illustrated in the graphic part:

in FIG. 1 - the overall design and arrangement of elements in the device of stabilization and voltage regulation,

in FIG. 2 - the body of the device for stabilization and voltage regulation.

The voltage stabilization and adjustment device consists of a housing in which an input circuit breaker 1 (Fig. 1) is integrated, which is responsible for finding the dimmer in operating mode, connected to automatic load switches 2 (Fig. 1), which is responsible for the operation of the dimmer. To the automatic load switches 2 (Fig. 1) are connected the automatic switches of the microcontrollers of the dimming modules 3 (Fig. 1) and the circuit breaker of the automated control unit 4 (Fig. 1), which allows protecting the power circuits of these units from short circuit. In the upper part of the device there is an electric energy meter 5 (Fig. 1), which is responsible for the data of the consumed line of street lighting installations of energy and sends information to the database for subsequent monitoring. The bypass switches 6 (Fig. 1), located to the right of the electronic energy meter 5 (Fig. 1), when switching them, completely turn off the power circuits of the device, which are responsible for the saving mode, so that the device functions in the event of a dimming module failure.

On the right, in the upper part of the device’s body there is an automated control unit 7 (Fig. 1), which allows the dimmer to function in automatic mode and receive remote dispatcher commands. In the lower part of the device housing is an autotransformer 8 (Fig. 2), which provides a stepwise voltage reduction.

On the surface of the housing there is a mode switch of unit 9 (Fig. 2), which allows you to switch it to the normal, saving, minimum modes. Power triac keys 10 (Fig. 2), allowing the microcontrollers of the dimming modules to connect the necessary windings of the autotransformer and thereby supply the necessary voltage to the output of the dimmer and to the lighting line. Light-signal indicators 11 (Fig. 2) located on the surface of the housing to the right of the operating mode switch of unit 9 (Fig. 2), by which the microcontrollers of the dimming modules indicate the results of testing and polling, as well as operating modes.

The voltage stabilization and regulation device works as follows: the voltage stabilization and voltage regulation device is installed nearby and connected to the power supply of the transformer substation. In turn, outdoor lighting lines are connected to it.

After installation, the voltage stabilization and adjustment device remains on in operation. For this, an introductory circuit breaker 1, automatic circuit breakers 2, an automatic circuit breaker 4, automatic circuit breakers microcontrollers dimming modules 3.

After applying voltage to the voltage stabilization and voltage regulation device, the GSM module communicates with the server. At the same time, it polls the status of all sensors from the I / O board and sends information about their status to the server.

In the absence of the possibility of communicating, the voltage stabilization and adjustment device operates in autonomous mode, fully ensuring the operability of the power unit according to predetermined combustion schedules (including the solar calendar and preset dimming levels). The voltage stabilization and adjustment device also accumulates in the permanent memory all the events occurring at the object. When communication is restored, the GSM module sends all stored events to the central server and maintains further communication with it to ensure real-time operation (telemetry), signaling statuses and states, as well as changing burning schedules at the request of the dispatcher. In case of insufficient temperature, the voltage stabilization and adjustment device automatically turns on the heater.

After applying voltage to the microcontrollers of the dimming modules (not shown in the drawing), the microcontrollers begin to test the power triac keys 10 for breakage and breakdown, as well as polling the connected sensors. After testing and polling, the microcontrollers of the dimming modules transmit information about testing and polling to the voltage stabilization and adjustment device via the RS-485 bus. Also, according to the results of testing and polling, the microcontrollers of the dimming modules indicate with the help of light-signal indicators 11 on the surface of the housing the results of testing and polling. Then the voltage stabilization and adjustment device goes into standby mode. In this mode, the dimming modules (not shown in Fig.) Are fully ready to work out the commands coming from the voltage stabilization and adjustment device.

Upon receipt of a command to turn on the lighting in the required mode from the voltage stabilization and adjustment device, the microcontrollers of the dimming modules using the power simistor keys 10 connect the necessary windings of the autotransformer 8 and thereby supply the necessary voltage to the output of the voltage stabilization and adjustment device and to the lighting line.

When changing the position of the bypass switches 6, the power circuits of the device are completely disconnected.

The mode switch of unit 9 operates in three modes: normal, saving, minimum, and allows you to mechanically or remotely set the desired mode of operation of lighting installations.

Automatic control and accounting of electricity, necessary to estimate the amount of electricity consumed in each operating mode, is carried out by installing an electricity meter in the device 5. Automatic monitoring of the state and functioning of both the device and street lighting networks is represented by an automated control unit 7.

The adopted technical solutions allow without significant modernization of outdoor lighting networks to reduce electricity costs by 40%, increase the life of lighting systems and lamps by stabilizing and regulating voltage.

Thus, the task is completed.
