Description

Electrical equipment panel, cabinet cooling device

technical field

The utility model relates to electric equipment, in particular to a cooling device for screens and cabinets of electric equipment.

Background technique

Electrical equipment screens and cabinets can be divided into high-voltage and low-voltage according to voltage levels, and can be divided into circuit breaker cabinets, isolation cabinets, capacitor compensation cabinets, DC screens, AC screens, protection device screens, communication screens, master control screens, etc. according to their uses. Some screens and cabinets are closed, and the equipment in many screens and cabinets is installed relatively tightly. The heat emitted by the equipment is easy to accumulate. Especially in summer when the door is opened to inspect the equipment, the inspector can feel that the temperature inside the screen will be very high, which is likely to cause damage to the equipment. The temperature rise will affect the service life and safety reliability. Most of the cooling methods currently used are to open holes on the top of the screen and cabinet for natural convection cooling, and some are equipped with fans and turned on for a long time to cool down, but the effect is not good.

Contents of the invention

The purpose of the utility model is to provide a cooling device for electrical equipment screens and cabinets with good cooling effect.

In order to achieve the above object, the technical solution adopted by the utility model is:

A cooling device for electrical equipment screens and cabinets, including a base, characterized in that: a power connector, a switch, a power indicator light, a spiral fuse, a temperature sensor with a temperature control switch and a fan are installed on the base; the power connector is connected in series with the switch , The power indicator light is connected in parallel to the power connector and both ends of the switch, and the spiral fuse is connected in series with the temperature sensor with temperature control switch and the fan, and then connected in parallel to both ends of the power indicator light.

According to the cooling device for the panel and cabinet of electrical equipment, it is characterized in that: three fans are installed on the base, and the three fans are connected in parallel.

The utility model organically combines a fan, a temperature sensor with a temperature control switch, a power indicator light, a spiral fuse, etc., and automatically turns on the fan according to the temperature change in the screen and the cabinet to accelerate the air flow in the screen and the cabinet, effectively Improve the air circulation in panels and cabinets, reduce the temperature of DC rectifier panels and cabinets, reduce equipment damage caused by temperature rise, improve power supply reliability, and ensure safe operation of equipment.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

A cooling device for electrical equipment screens and cabinets, as shown in Figures 1, 2, and 3, includes a base 7 on which a power connector 1, a switch 2, a power indicator light 3, a spiral fuse 4, and a belt The temperature sensor 5 and the fan 6 of the temperature control switch; the power connector 1 is connected in series with the switch 2, the power indicator light 3 is connected in parallel with both ends of the power connector 1 and the switch 2, the spiral fuse 4 is connected with the temperature sensor 5 and the fan with the temperature control switch 6 is connected in parallel to both ends of the power indicator light 3 after being connected in series. In this embodiment, three fans 6 are installed on the base 7, and the three fans 6 are connected in parallel.

The utility model is composed of a power connector, a power indicator light, a switch, a spiral fuse, a temperature sensor with a temperature control switch, a fan and a base. The base is installed on the top of the screen through a separate bracket (see Figure 4), which is convenient for maintenance; When there is a DC power supply in the power distribution room, the battery inverter output power supply can be used to improve reliability; the number of fans adopts three types that can form significant airflow; the fan start mode adopts a temperature control switch that can actively arrange the start and stop of the fan according to the ambient temperature Bootstrap.

When making this utility model, install three fans side by side at the middle position of the base, install the temperature sensor with temperature control switch at the middle position on the left side of the base, and install the switch, power indicator light, and spiral fuse at the lower left corner of the base Location. The electrical connection relationship between each component is: the power connector is connected in series with the switch, the power indicator light is connected in parallel at both ends, the spiral fuse is connected in series with the temperature sensor with temperature control switch, and the fan group with three fans connected in parallel and then connected in parallel to both ends of the power indicator light.

In the utility model, the fan plays the role of strengthening the air circulation in the electrical equipment screen and the cabinet, reducing the temperature in the screen and the cabinet; the temperature sensor with a temperature control switch automatically connects the circuit when the temperature reaches the upper limit, and starts the fan to complete the operation. The purpose of cooling; the power indicator light is used to prompt the fan when it is working; the spiral fuse is used for protection.

When the utility model needs to work, first set the temperature upper limit value, when the temperature sensor measures the temperature in the screen and the cabinet reaches the upper limit value, automatically close the temperature control switch, start the fan to cool down, when the temperature is lower than the upper limit again When the limit value is exceeded, the temperature control switch is automatically disconnected, so as to realize the automatic control of the fan and achieve the purpose of energy saving and cooling.
