Description

Switch for AC lighting or

heater

The proposed utility model relates to the field of electrical engineering, and more precisely, to switches of lighting and heating devices operating on alternating voltage.

Well-known switches of lighting and heating devices, which contain one single-wire contact switchboard and a button, by pressing which the contacts of the contact pair are connected or disconnected. Such a switch is mounted in one of two network wires, through which electrical voltage is supplied to a lighting device, for example, to an electric lamp, or to a heating device, for example, to an electric stove.

Such a switch performs only the function of turning on the electric voltage to the electric lamp and disconnecting the voltage from the electric lamp. Such a switch cannot regulate the magnitude of the voltage supplied to the electric device.

The voltage regulation on the electric lamp can be performed using various types of regulators, including resistors (constant and variable), transformers, which sometimes also require the use of additional switches, etc. Such regulators are quite expensive.

The prototype of this utility model is a circuit breaker with one single-wire contact pair (GOST 7397.0 - 89. Circuit breakers for household and similar fixed installations. State Committee for Product Quality and Standards Management, Moscow, 1990, p. 74, Fig. 1). Its disadvantage is the inability to adjust the voltage on the lighting device and thereby reduce the power consumed by the lighting or heating device.

The technical task of this utility model is to provide the ability to regulate the electrical power transmitted to the load, while it becomes possible to save electricity and the ability to control the amount of usable power supplied.

The essence of the utility model lies in the fact that the switch for an alternating voltage lighting or heating device contains a single-wire contact pair and (further distinctive features) means for reducing the shock in the lighting or heating device connected in parallel with a single-wire contact pair.

In addition, the essence of the utility model lies in the fact that the means for reducing the jam in the lighting or heating device can be made in the form of a diode.

In addition, the essence of the utility model lies in the fact that the switch may contain means for remote control of a single-wire contact pair.

Moreover, the essence of the utility model is that a single-wire contact pair and means for remote control of a single-wire contact pair are a relay containing one contact group of two contacts.

In addition, the essence of the utility model is that the means for reducing the current 3 of the lighting or heating device may contain a diode connected in series and an additional single-wire contact pair.

In addition, the essence of the utility model is that the switch may include means for remote control of a single-wire contact pair and means for remote control of an additional single-wire contact pair.

In addition, the essence of the utility model is that a single-wire contact pair and means for remote control of a single-wire contact pair can be made in the form of a first additional relay containing one con-1-act group of two contacts, and an additional single-wire contact pair and

means for remote control of an additional single-wire contact pair can be made in the form of a second additional relay containing one contact group of two contacts.

Regulation of power transmitted to the load is based on the fact that if there is current. supplying the load passes through the diode, then the transmitted power is reduced by about half, since the diode does not pass one half-wave of a sinusoidal alternating supply voltage

The load 8 is also connected to the second network wire 2. The single-wire contact pair 5 has a button, which, when pressed, closes or opens the contacts of the contact pair.

In FIG. 2 shows a switch 3, in which the means 6 for reducing current in the lighting or heating device is made in the form of a diode 9, preferably a semiconductor diode.

In FIG. 3 shows a switch 3 in which there is means 11 for remote control of a single-wire contact pair 5, which has a control input 12 of means 11 for controlling a single-wire contact pair 5. The control input 12 is connected, for example, to a button with a battery in series, which are not shown and may be located in another room or in another building.

an electric relay 13, which has an electric winding 15 and a contact group of two contacts 14, and the contacts 14 of the relay 13 are included instead of a single-wire contact pair 5 and connect the alternating voltage to the load 8 or disconnect it from the load 8. The winding 15 of the relay 13 is connected to the control input 12.

In FIG. 5 shows a switch that contains a single-wire contact pair 5. to which parallel connected diode 9 and an additional single-wire contact pair 10. Contact pair 5 and diode 9 are connected through input 4 to the first network wire 1, through which an alternating voltage is supplied. The contacts of the contact pairs 5 and 10 are connected through the output 7 of the switch 3 to the load 8, which is also connected to the second network wire 2.

In FIG. 6 shows the switch 3, the same as in FIG. 5, but which comprises means 11 for remote control of a single-wire contact pair 5. and means 16 for remote control of an additional single-wire contact pair 10. A control input 12 is connected to means 11 for remote control of a single-wire contact pair 5, and control input 17 is connected to means 16 for remote control of an additional single-wire contact pair 10. The control inputs 12 and 17 are each connected, for example, to the knots connected in series and placed in another building PKE and a battery that supplies current to the coils 14 relays 18 and 19 for connecting or disconnecting relay contacts 14.

In FIG. 7 shows a switch 3, the same as in FIG. 6, but the means 11 for remote control of a single-wire contact pair 5 and the contact pair 5 are made in the form of a first additional relay 18 having a winding 15 and a contact group of two contacts 14. Means 16 for remote control of an additional single-wire contact pair 10 and an additional single-wire contact pair 10 is made in the form of a second additional relay 19 having a winding 15 contact group of two contacts 14.

juim Switch 3 shown in FIG. 1, works as follows. An alternating voltage is connected to the first and second network wires 1 and 2. The switch 3 allows you to transfer the full current and the full possible power to the load 8 when the contacts of the contact pair 5 are closed. When the contacts of the contact pair 5 are open, less power is transmitted to the load 8, since the means 6 reduces the current in the load compared to the current, which flows when contact pair 5 is on. Such a switch can be used, for example, in storage facilities, in basements of houses where there is no natural lighting and where artificial lighting should be constant, but when there are no people, the brightness of Broadcasting may be reduced. In normal times, when there are no people in the storage, the single-wire contact pair 5 is turned off (open). When a person enters the store, he turns on a single-wire contact pair 5, while the brightness of the lighting device increases.

Thus, if the consumer uses a lighting device and can do with less light, then he turns off the contact pair 5. Or, such a decrease in the light of the lighting device may be needed in the corridor or on the stairwell at night, while in the daytime in the corridor where there is no natural lighting, there will be the maximum possible illumination when the contact pair 5 is on. In all cases when the contact pair 5 is off, there will be energy savings, in addition, the life of the lighting device will increase A cartridge for a lamp due to the lower heating them. When the contact pair 5 is off, the switch 3 also performs the function of a short circuit fuse.

coming from the control center to the coil 15 of the relay 18 or 19, can close or open the contact groups 14 of the relay 18 or 19.

The feasibility of the utility model is confirmed by the fact that for the manufacture of the circuit breaker, a known circuit breaker can be used on one single-wire line with one contact pair or on two single-wire lines with two contact pairs, into which the diode is mounted and in which the necessary connections are made. As a diode, a diode can be selected that is suitable for the mains voltage (for example, for a 220 V network, the voltage should be 400 V) and for the current consumed (for a 100 W lighting lamp, it is necessary to turn on a diode designed for a current flow of 0, 5 A). Thus, to implement the utility model, well-known elements and known technologies are used.

The proposed utility model can be used to control the power consumed by the lighting network of corridors and stairwells of the entrance of a residential house or basement or storage, if the lighting network is turned on by the center, -1i: from the same place, for example, from the control room from the remote control management. In this case, of course, the diode must be sufficiently powerful (or several diodes connected in parallel can be applied).

When using the proposed switch, it is also necessary to ensure that the relevant requirements for the level of illumination in the rooms where the lighting is turned on with the proposed switch are met, and it must be in the forks. that the level of illumination can in some cases be reduced, for example, at night or after hours, as indicated in the relevant regulatory documents.

In FIG. 3 shows a switch 3, which has means 11 for remote control of a single-wire contact pair 5. The control input 12 receives SIGNS1 to turn on (close) and turn off (open) the contact pair 5. Thus, it is possible to control the lighting device (load 8) from another rooms, for example, control the artificial lighting of the corridors and stairwells there. where there is no natural light, while at night it is possible to reduce the illumination by applying a signal from a control room.

In FIG. Figure 4 shows a switch where the signal for switching the level of illumination is fed to the winding 15 of the relay 13, while the contacts 14 of the relay 13 are closed or opened.

In FIG. Figure 5 shows switch 3, with which you can stop the supply of voltage to the load completely (both single-wire contact pairs 5 and 10 are open), turn on the full voltage to the load (contact pair 5 is closed), or turn on 1H for one half wave of a sinusoidal voltage to the load ( contact pair 5 is open, and contact pair 10 is closed). Such a switch can be used on lesnichnyh cells of residential buildings, which are illuminated by natural light during the day, in the evening they can be illuminated with artificial light at full brightness, and at night they can be illuminated using the same lighting devices, but with a reduced brightness. Turning on the lighting and switching it can be done by residents.

On the . 6 shows a switch 3 similar to that shown in FIG. 5. but which is controlled remotely by control inputs 12 and 17, respectively connected to means 11 and 16 for remote control of a single-wire contact pair 5 and 10. Such a switch can be controlled from a control center for house maintenance.
