Abstract
The utility model provides a rapid pressure releasing apparatus for arcing in a high tension switchgear. The rapid pressure releasing apparatus comprises pressure releasing channels which are arranged in a breaker chamber, a bus-bar chamber and a cable outlet chamber. An opening of each pressure releasing channel is arranged above a cabinet body, and each opening is provided with a pressure releasing cover plate. One side of each pressure releasing cover plate is fixed at one side of the opening of each pressure releasing channel through a hinge device, and the other side of the pressure releasing cover plate is fixed at the other side of the opening of each pressure releasing channel through a clamp device. Each clamp device is a positioning clamp bolt. Each positioning clamp bolt is composed of a clamp bolt and a clamp spring, wherein the clamp bolt is fixedly arranged on one pressure releasing cover plate, the clamp spring is fixedly arranged at one side of the opening of each pressure releasing channel corresponding to the clamp bolt, and the clamp bolt is clamped in the clamp spring. As one side of each pressure releasing cover plate adopts one clamp device, high-pressure arcing gas can be successfully exhausted out of the cabinet body by bursting through the pressure releasing cover plates, and explosive gas is prevented from quickly leaking from the from and rear parts of the switchgear to hurt operators.
Description
Technical field
The utility model relates to a kind of high-tension switch cabinet, is a kind of high-tension switch cabinet arcing quick pressure relief device specifically.
Background technology
Choose application in the complete high voltage switchgear design of 10kV (35KV), the system of production.Although voltage switchgear itself should possess machinery " five anti-" function, with regard to its function, also can't reach perfect.
Be divided into circuit breaker, bus-bar room, cable outlet chamber, secondary meter chamber etc. by function in 10kV (35KV) high-tension switch cabinet.Generally normal in service be impossible produce arcing, primary cut-out can trip under normal circumstances when external load short circuit or overloading, lower routine situation may cause fatal destruction to switch cubicle;
1, circuit breaker second protection fault (normally separating brake);
2, device interior self ageing of insulation (being subjected to moist serious);
3, other factors (the design peace is apart from some defect is arranged).
The appearance of above-mentioned situation all likely causes inner arcing, and each device fabrication enterprise designs routinely usually; Establish three pressure relief openings makes of the fixing routine of metal cover board (nylon bolt or plastic bolt) at the switch cubicle top; If three pressure relief opening metal cover board (breaker chamber, bus-bar room, cable outlet chamber) pressure release passages, gas backs down metal cover board when producing inner arcing, and gas releases thus and reaches the pressure release purpose.But there is certain shortcoming in this structural design, is mainly arcing gas when not reaching analog value or having reached analog value, due to nylon bolt or plastic bolt, more firmly can not effectively open the pressure release metal cover board, causes and performs practically no function; Perhaps pressure relief plate is rushed to open, and causes metal cover board to cause and throws to space, may cause casualty accident after falling.
The utility model content
The purpose of this utility model is to provide a kind of quick pressure relief device, in order to solve the technological deficiency that exists in existing product.
The utility model is achieved through the following technical solutions:
a kind of high-tension switch cabinet arcing quick pressure relief device, comprise cabinet, include breaker chamber in described cabinet, bus-bar room and cable outlet chamber, described bus-bar room is arranged on the centre of described breaker chamber and described cable outlet chamber, described breaker chamber, bus-bar room and cable outlet chamber are provided with pressure release passage, the opening of described pressure release passage all is arranged at the top of cabinet, described opening is provided with the pressure release cover plate, one side of described pressure release cover plate is fixed on a side of the opening of described pressure release passage by hinge means, the opposite side of described pressure release cover plate is fixed on the opposite side of the opening of described pressure release passage by clamping apparatus.
Further, described clamping apparatus is the location snib, described location snib is comprised of card bolt and card spring, described card bolt is fixed on described pressure release cover plate, described card spring fitting is fixed on a side of the opening of the described pressure release passage corresponding with described card bolt position, and described card bolt card is connected in the card spring.
Further, the below of described pressure release cover plate is provided with waffle slab, and described waffle slab is positioned at described pressure release passage.
Further, the single grid of described waffle slab is square, and the width of described single grid is 12.5mm.
Further, described waffle slab is the metal grill plate.
Further, the open angle of described pressure release cover plate is greater than 100 degree.
A side due to the pressure release cover plate in the utility model has adopted clamping apparatus, therefore when the inner generation of high-voltage board arcing gas, can back down smoothly clamping apparatus, and make pressure release cover plate open angle surpass 100 degree, avoided more firmly can not opening the pressure release cover plate due to nylon bolt or plastic bolt, guaranteed the unobstructed of pressure release passage, prevented that damp from releasing the injury operating personnel rapidly before and after switch cubicle; Simultaneously below the pressure release cover plate, set up the metal grill plate one in pressure release passage, can prevent that foreign matter from directly entering charged interval, further protected the high-voltage switch cabinet body internal component.
