Description

Intelligent start and stop system for shutters in high pressure chamber

technical field

The utility model belongs to the technical field of shutter control in a high-voltage chamber, in particular to an intelligent start-stop system for shutters in a high-pressure chamber.

Background technique

Substation equipment inspections are divided into routine inspections, comprehensive inspections, professional inspections, light-off inspections and special inspections. During various inspections, it is required to check and ventilate the humidity of the high-pressure room. The humidity in the high-voltage room does not exceed 75%. During the inspection, the operation and maintenance personnel check the hygrometer in the high-voltage room, open and close the shutters and doors in the high-voltage room to ventilate and drive away the tide, so as to reduce the humidity in the high-voltage room and ensure that the humidity in the high-voltage room of the substation is within the acceptable range. The disadvantage of the artificial ventilation tidal drive method is that the efficiency is not high, and the operation and maintenance takes a long time, which affects the quality and efficiency of the work. At the same time, small animals enter during the opening of the high-pressure chamber door, which directly affects the safety of production. This requires an intelligent device that can automatically ventilate to improve the indoor operating environment without fan noise to improve the level of operation and maintenance management.

For example, the invention with application number CN103458659B discloses electric cabinet shutters. There are two electric cabinet shutters, which are respectively set on a pair of adjacent side surfaces of the electric cabinet housing; preferably, the heights of the two shutters are different. ; One is located at the lower part of the side of the power cabinet, and the other is located at the upper part of the side of the power cabinet; thereby increasing the airflow movement space inside the power cabinet. However, the blinds cannot be closed automatically, and if the humidity in the power cabinet exceeds the value in rainy weather, an electric safety accident will be caused.

Utility model content

In order to solve the above-mentioned technical problems, the utility model provides a low-lying substation high-voltage room or other auxiliary rooms, which solves the problems caused by the long-term high humidity in the high-voltage room and the condensation of the equipment in the cabinet, which reduces the insulation of the equipment and discharges. The safety hazard of equipment explosion, the intelligent start-stop system of high-voltage room shutters to ensure the personal safety of operation and maintenance personnel and equipment safety.

The utility model discloses an intelligent start-stop system for shutters in a high-voltage chamber, which comprises a power switch, a single-phase switch, an environment controller, a three-phase AC relay, and a motor shutter. The power switch is a three-phase power switch; one end of the environment controller passes through The single-phase switch is connected to the three-phase power switch, and the other end of the environmental controller is connected to the motor shutter through the three-phase AC relay; the outlet port of the three-phase power switch is connected to the three-phase AC relay .

Further, the incoming line port of the three-phase power switch is connected to the outgoing line end of the low-voltage panel of the substation.

Further, a live wire of the three-phase power switch is connected in parallel with the single-phase switch.

Further, the single-phase switch is a circuit breaker.

The beneficial effect of the utility model is that the intelligent start-stop system for the blinds of a high-voltage room provided by the utility model uses a three-phase power switch and a single-phase switch to supply power to the whole system; the lower limit of the humidity of the environmental controller is set to 73%, the upper limit 75%, the two-way contact of the environmental controller is higher than the set starting value to selectively turn on the circuit, and is automatically disconnected when it is lower than the set starting value.

The present invention is suitable for the high-voltage room of low-lying substation or other auxiliary rooms, and solves the potential safety hazard of explosion of substation equipment caused by the reduction of equipment insulation and discharge due to the long-term high humidity of the high-pressure room, and the equipment in the cabinet is easy to produce, ensuring the safety of operation and maintenance personnel Personal safety and equipment safety.
