Description

An automatic protective frame for power distribution room

technical field

The utility model relates to the technical field of electric equipment, in particular to an automatic protective frame for a power distribution room.

Background technique

The power distribution room and the control room in the distribution station are connected to each other. There are rows of power distribution cabinets and control cabinets in the room. The cabinets are connected by cables, and the cabinets must be strictly grounded and protected. Connecting, rodents and small animals often enter the power distribution room, control room or crawl on the distribution transformer, resulting in alternating short circuit of the transformer porcelain bottle terminal string, not only burning out the equipment, but also often causing various substation operation accidents, amplifying power outages, and threatening power safe operation of the system. "Specification Requirements for Power Distribution Room" stipulates: "6.1.3 Power distribution room and control room should be able to be naturally ventilated, and measures should be taken to prevent the intrusion of rain and snow and animals." That is, the indoor cannot be closed, and natural ventilation is required, so One of the key points of the daily protection of the open power distribution room is to prevent rodents and small animals from intruding and damaging cables, and rain and snow from intruding into the power distribution room.

The operation and maintenance teams under the State Grid in the northern region inspect dozens of power distribution stations per shift, and each power distribution station has several power distribution rooms. The above-mentioned protection tasks are relatively heavy. The inner side uses wooden boards, metal plates and other objects as barriers to block foreign objects. The industry standard height is 50cm. The existing problems are: 1. Although it has anti-jumping effects on rodents and small animals, the barriers are all non-networked bodies. Whether the board is toppled over and whether it is in place cannot be controlled in real time, and maintenance personnel will forget to put back the baffle from time to time, and the protective effect will be lost; 2. Each substation is more than half an hour away. To check the return status of the baffle, dozens of It takes half a day to inspect each substation one by one, and the workload of the inspectors is heavy; 3. In case of rainy and snowy weather, the power distribution room should prepare measures to prevent rainwater intrusion. The rain is too heavy. Although the indoor monitoring can grasp the situation on site, the inspectors cannot arrive at the first time, and the rain and snow will still flow in. Seriously, it will cause water to enter the busbar of the voltage cabinet and detonate the circuit breaker.
