Abstract
A high voltage switch cabinet with a pressure relief device belongs to the field of high voltage switch cabinets and comprises a high voltage switch cabinet body, and a pressure relief passage is arranged above the cabinet body; the high voltage switch cabinet with a pressure relief device is characterized in that a pressure relief device is arranged above the pressure relief passage and comprises a pressure relief supporting plate, a pressure relief cover plate and a side plate, the pressure relief supporting plate is hinged with the tail end of the pressure relief cover plate, two sides of the pressure relief cover plate are movably connected with the side plate, and a dustproof net is arranged in the direction in front of the pressure relief cover plate. By heightening the pressure relief passage, the safety distance of a screen top bus of a bus compartment in the cabinet body on the cabinet top is extended; as the pressure relief supporting plate with ventilating and heat dissipation holes and the dustproof net is arranged, heat generated inside during the operation of the switch cabinet can be timely dissipated, thus prolonging the service life of all insulators and components in the cabinet body; and simultaneously, the dustproof net can prevent excessive outside dust from entering the cabinet and scattering onto the insulators, which reduces the insulation.
Description
Technical field
The utility model provides a kind of high-tension switch cabinet with pressure relief device, especially a kind of high-tension switch cabinet with ventilation, heat radiation, dustproof pressure relief device.
Background technology
At present; The 35kV high-tension switch cabinet is equipped with pressure relief device above circuit breaker cart chamber, bus-bar room and cable vault, when circuit breaker or bus-bar room generation internal fault electric arc, follow the appearance of electric arc; The switch cubicle air pressure inside raises; The pressure release metallic plate of top installing will be opened, and release pressure and gas are to guarantee the safety of operating personnel and equipment.But the pressure release metallic plate here is dull and stereotyped, is not with ventilating heat dissipating hole.Switch cubicle is in the process of putting into operation, and inner meeting produces a large amount of heats, because sealing all around; Heat can not in time shed; Can have a strong impact on circuit breaker cart after heat is too high, the performance of insulating material such as contact box, sleeve pipe, heat-shrink tube, thus reduce its useful life.
The utility model content
According to the deficiency of above prior art, the technical problem that the utility model will solve is: a kind of have pressure release effect, good result of ventilating heat dissipation are provided, also have the high-tension switch cabinet of the band pressure relief device of dustproof effect.
The utility model solves the technical scheme that its technical problem adopted: a kind of high-tension switch cabinet with pressure relief device; Comprise the high-tension switch cabinet cabinet, the cabinet top is provided with pressure release passage, it is characterized in that: the pressure release passage top is provided with pressure relief device; Pressure relief device comprises pressure release supporting bracket, pressure release cover plate and side plate; Pressure release supporting bracket and pressure release cover panel end are hinged, and pressure release cover plate both sides and side plate flexibly connect, and cabinet the place ahead of pressure release cover plate is to fixedly installing Air Filter.
On the cabinet of high-tension switch cabinet, especially the cabinet rear of circuit breaker cart chamber, bus-bar room and cable vault lets pressure release passage increase and makes the pressure release cover plate become an inclined-plane to mounting strap pressure release supporting bracket, is convenient to heat radiation, pressure release, Air Filter is set can has dust reduction capability.Pressure release cover plate cabinet rear is to hinged with supporting bracket, and also for flexibly connecting, cabinet the place ahead is to being fixed by bolts on the cabinet in both sides.
Wherein preferred version is:
Described pressure release supporting bracket top is provided with ventilating heat dissipating hole.The inner heat that produces of cabinet can outwards be evacuated through ventilating heat dissipating hole in the running.
Triangular in shape or the wedge shape of described side plate.Can guarantee that pressure release passage is unobstructed.
The beneficial effect that high-tension switch cabinet had of the utility model band pressure relief device is: through pressure release passage is increased, especially increased the safe distance that bus-bar room flat-top bus pushes up cabinet in the cabinet; Installation has the pressure release supporting bracket of ventilating heat dissipating hole and Air Filter; Can make the heat of inner generation in the switch cubicle running in time obtain evacuating; Prolong the useful life of interior each insulating part of cabinet and components and parts; Simultaneously Air Filter can prevent that extraneous too much dust from getting in the cabinet, is scattered on the insulating part and causes the insulation short circuit.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the Air Filter of the utility model;
Wherein: 1, cabinet 2, Air Filter 3, pressure release cover plate 4, side plate.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Like Fig. 1, shown in Figure 2; High-tension switch cabinet cabinet 1 top is provided with pressure release passage; The pressure release passage top is provided with pressure relief device, and pressure relief device comprises pressure release supporting bracket, pressure release cover plate 2 and side plate 4, and pressure release supporting bracket and pressure release cover plate 3 are terminal hinged; Pressure release cover plate 3 both sides and side plate 4 flexibly connect, and cabinet the place ahead of pressure release cover plate 3 is to fixedly installing Air Filter 2.
Pressure release supporting bracket top is provided with ventilating heat dissipating hole, and the inner heat that produces of cabinet can outwards be evacuated through ventilating heat dissipating hole in the running.
Circuit breaker cart chamber, bus-bar room and cable vault in the utility model middle-high voltage switch cabinet, and the electric component of other settings is common prior art, the technical staff is grasped by the industry.
Its principle is:
When closed high-tension switch cabinet was in normal operating conditions, pressure release cover plate 3 kept closed state with cabinet 1.The inner heat that produces can outwards be evacuated through ventilating heat dissipating hole in the running.The ventilating heat dissipating hole place also is welded with Air Filter 2, prevents that extraneous too much dust from getting in each compartment.When breaking down in the cabinet 1; The high temperature and high pressure gas that produces impacts pressure release cover plate 3, and several places of flexible connection will be by gases at high pressure jack-up, and pressure release cover plate 3 is opened as opening the door fully; High temperature and high pressure gas is also instantaneous to be released, and prevents serious accident.
Claims (3)
1. high-tension switch cabinet with pressure relief device; Comprise the high-tension switch cabinet cabinet, the cabinet top is provided with pressure release passage, it is characterized in that: the pressure release passage top is provided with pressure relief device; Pressure relief device comprises pressure release supporting bracket, pressure release cover plate and side plate; Pressure release supporting bracket and pressure release cover panel end are hinged, and pressure release cover plate both sides and side plate flexibly connect, and cabinet the place ahead of pressure release cover plate is to fixedly installing Air Filter.
