Box-type transformer for transformer substation

Abstract

The invention discloses a box-type transformer for a transformer substation, and belongs to the field of box-type transformers. In the use process of the box-type transformer for the transformer substation, dynamic balance of alcohol steam exists in a space formed by communicating a transition cavity, a volatilization through hole and a sealing cavity, namely, the concentration of the alcohol steam volatilized in the position reaches the maximum value; when birds nest on the bearing plate, alcohol mixed with the bird repellent in the transition cavity begins to volatilize quickly and is used for repelling the birds, after the birds fly away, the compression spring in a compressed state can push the bearing plate back to the original position, the transition cavity and the volatilization through hole are sealed again, meanwhile, the insect repellant stored in the storage end also recovers to the sealed state, the effective use time of the bird repellent can be greatly prolonged, the bird repellent does not need to be frequently replaced by technicians, and the influence of birds on electric equipment in a power station is reduced.

[0002] Trees are often planted around large substations, and birds often inhabit and nest around substations, which can easily cause line flashovers and line trips, and at the same time cause harm to birds

At present, the more common bird repellents on the market can be divided into repelling birds through mirrors and bird thorns, and there are also infrared or laser bird repellents. The above-mentioned bird repellents can achieve certain bird repelling effects. , but there is a single function and a single way of repelling birds. As time goes by, the effect of repelling birds will decrease. Some bird repellents will easily frighten birds and cause abnormal behavior of birds, which is not conducive to the protection of animals.

[0003] At the same time, the nesting speed of some birds is very fast, and most of the existing bird repelling devices are fixed settings. There may be birds nesting between the two bird repelling devices. Once the birds build their nests, the harm will be greater : 1) Birds build nests. In spring, birds begin to build nests, lay eggs, and hatch on transmission line towers. Most of them are magpies, crows, goshawks and other birds. These birds hold branches, wire, firewood, etc. in their mouths. When flying back and forth on the road, when iron wires and other objects fall between the cross arm and the wire, it will cause a line fault. When the wind blows, the bird's nest on the pole tower will be blown away by the wind and fall on the live wire or hanging bottle, which will cause a short circuit ground fault. ;2) Birds fly. Larger birds such as black storks have a body length of more than 1m and larger wings. Larger birds or birds flying between wires may cause phase-to-phase short circuit or single-phase Ground fault; 3) Bird droppings flashover, bird droppings (especially the owl's thin feces) pollute the bottle string, and flashover is prone to occur when the air is humid and foggy, and the bird stands on the upper cross arm of the bottle string and defecates downward And when it flows down the bottle string, it will cause single-phase grounding, or the bird droppings will blow to the charged body with the wind, causing air gap breakdown, causing failure

[0004] Most bird repellents are green and pollution-free biological types. Bird repellents are generally processed from pure natural raw materials (or equivalent to natural raw materials). The special fragrance of the nervous system and respiratory system, the bird will fly away after smelling it, and will not come back within its memory period. As a green and environmentally friendly method of repelling birds, bird repellent has been widely used in various agriculture and aviation, etc. However, the effective time of the bird repellant is short, and technical personnel are required to replace the expired bird repellent to achieve continuous bird repellent work. For areas with many power facilities such as substations, for safety reasons, Technicians cannot frequently replace the failed bird repellant, let alone cut off the power supply frequently in order to replace the bird repellent. The traditional method of using bird repellent is difficult to apply to substation areas with many power equipment
