Technical Field
The utility model relates to a vacuum circuit breaker technical field, concretely relates to protection type high pressure vacuum circuit breaker.
Background
The vacuum circuit breaker is named because the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small volume, light weight, frequent operation and no need of maintenance, is more popular in the distribution network, can be used for protecting and controlling electrical equipment in industrial and mining enterprises, power plants and transformer substations, the circuit breaker is particularly suitable for use places requiring no oil, less maintenance and frequent operation, the circuit breaker can be arranged in a middle cabinet, a double-layer cabinet and a fixed cabinet to be used for controlling and protecting high-voltage electrical equipment, the existing vacuum circuit breaker can be exposed outside for a long time when in use, and is damaged due to long-time wind blowing and sunshine and high-temperature influence, when the sealing ring or other parts on the vacuum circuit breaker are damaged, the leakage of the insulating oil can be caused, so that the inside of the oil circuit breaker is lack of oil and the arc can not be extinguished, if the oil breaker is not found in time, once the oil breaker acts, the vacuum breaker is inevitably exploded.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is in providing protection type high-pressure vacuum circuit breaker to solve present high-pressure vacuum circuit breaker and expose in the external world for a long time, the problem of damage probably appears in its spare part.
In order to solve the technical problem, the utility model provides a following technical scheme: the protective high-voltage vacuum circuit breaker comprises a high-voltage vacuum circuit breaker body and a box body, wherein the top of the box body is open, a plurality of supporting rods are fixedly connected to the top of the box body, the top ends of the supporting rods are fixedly connected with a same shielding plate, the inner bottom of the box body is fixedly connected with a supporting plate, a plurality of ventilation holes are formed in the supporting plate, a fan with an upward air outlet is arranged in the box body, and the fan is positioned below the supporting plate; the high-voltage vacuum circuit breaker body is installed in the backup pad, fixedly connected with battery on the box, and the battery passes through signal of telecommunication with the fan and is connected.
The utility model discloses the theory of operation: install the box during use, after the hot and high-pressure vacuum circuit breaker body operation of weather generates heat, start the fan, because the interior bottom fixedly connected with backup pad of box, be equipped with the ventilation hole in the backup pad, and the fan sets up in the backup pad below, and the air outlet of fan up, so when starting the fan, the battery provides the electric energy for the fan, the fan is upwards bloied during operation, the wind that the fan blew off blows to the backup pad top and accelerates the ascending velocity of air around the high-pressure vacuum circuit breaker body through the ventilation hole, air flow rate accelerates the uncovered outflow of the heat that will empty circuit breaker body after will giving out and passes through the box top. Simultaneously, a plurality of supporting rods are fixedly connected to the top of the box body, and a shielding plate is fixedly connected to the supporting rods, so that when sunshine shines and rains, the shielding plate shields the high-voltage vacuum circuit breaker body.
The utility model has the advantages that: 1. this scheme separates the bottom of high-pressure vacuum circuit breaker body and box through the interior bottom at the box, sets up the fan between high-pressure vacuum circuit breaker body and box, accelerates the radiating rate of high-pressure vacuum circuit breaker body in the box through the fan operation, reduces its body temperature, avoids when being in higher temperature for a long time, and its spare part oxidation rate accelerates, has shortened life. 2, shelter from the high-pressure vacuum circuit breaker body through the shielding plate, avoid it directly to receive sunshine to shine and rainwash, the effectual possibility of damaging that has reduced its spare part and expose when external for a long time.
Furthermore, the shielding plate is composed of two inclined plates, and the top ends of the two inclined plates are fixedly connected. Its purpose is through this kind of setting when being convenient for rainy day, the rainwater flows away along two blocks of swash plates.
Furthermore, the upper surface of the shielding plate is fixedly connected with a solar cell panel, and the solar cell panel is connected with the storage battery through a cable. The solar cell panel is used for supplementing electric energy to the storage battery, and resources are saved.
Furthermore, a cavity is reserved inside the shielding plate, and tinfoil is filled in the cavity. The solar energy heat collector has the advantages that under clear weather, heat in sunlight can be effectively reflected through the tin foil, and the temperature rise in the box body caused by direct sunlight is avoided.
Furthermore, the outer surface of box encloses there are two solid fixed rings. Its purpose through solid fixed ring increase box tightness, avoids high-pressure vacuum circuit breaker to appear the spare part in disorder when exploding because of the accident and flies.
Further, the supporting plate is made of a screen plate. The air-permeable cylindrical net plate is better in air permeability, and more air blown out from the fan can pass through the air-permeable cylindrical net plate.
