Abstract
The utility model relates to a switch cabinet structure, which comprises a circuit breaker cavity. The utility model is characterized in that a plurality of through holes are arranged in local positions of an insulation partition plate arranged at the top part of the circuit breaker cavity, a pressure relief passage is arranged above the through holes, an outlet of the pressure relief passage is arranged on the top wall of the cabinet body, and a railing type cover plate in hinged type connection is arranged on the outlet. The utility model has the advantages that after the pressure relief passage communicated with the outside is additionally arranged inside the cabinet body, the pressure of the switch cabinet is raised through the combustion of the generated electric arc even when faults such as in-phase (phase-to-ground) short circuit, insulation, breakdown in the air and the like of the switch cabinet occur, the pressure gas can prop open the cover plate to be fast exhausted through the pressure relief passage, the gas can be effectively released for lowering the pressure, and the goals of ensuring the safety of operators and the switch cabinet can be reached.
Description
[technical field]
The utility model belongs to a kind of high-voltage switch gear cabinet, relates in particular to a kind of cabinet body structure of XGN17 switch cubicle.
[background technology]
At present, in XGN17 switch cubicle structure, circuit breaker is installed in the interior airtight relatively chamber of cabinet, therefore, when circuit breaker breaks down, arc burning rear chamber air expanded by heating, the interior pressure increases, blast easily, and cause whole switch cubicle paralysis, have serious potential safety hazard.
[summary of the invention]
For overcoming the prior art above shortcomings, the utility model aims to provide a kind of switch cubicle structure, when the switch cubicle of this structure runs into circuit breaker and breaks down, after arc burning makes the chamber atmosphere expanded by heating, can discharge the air of expansion rapidly, reduce interior the pressure, and effectively avoid the generation of explosion accident.
Realize that the above-mentioned purpose technical scheme is as follows, this switch cubicle structure, comprise the circuit breaker chamber, it is characterized in that: on the local location of the insulating barrier of described circuit breaker chamber roof, be provided with a plurality of through holes, the through hole top is provided with a pressure release passage, and the outlet of pressure release passage is located on the roof of cabinet, has the fence type cover plate that a radial type connects in the outlet.
During concrete enforcement, a side of described cover plate is fixed by metal fastenings, and opposite side is located by nylon fasteners.
Beneficial effect: compared with prior art, the utility model by set up in cabinet inside one with the extraneous pressure release passage that communicates after, even circuit breaker breaks down, the internal arc burning raises the pressure in the chamber, pressure gas can back down cover plate and discharge rapidly through pressure release passage, effectively discharge gas and reduce pressure, reached and guaranteed operating personnel and switch cubicle purpose of safety.
[description of drawings]
Fig. 1 is the structural representation of an embodiment of the utility model.
Among the figure: pressure release passage 1, pressure release passage wall 2,3,4,5,6,7, insulating barrier 8, circuit breaker chamber 9.
[embodiment]
Referring to Fig. 1, K is to the front that is switch cubicle among the figure.The bottom, left side of this switch cubicle is a circuit breaker chamber 9, and circuit breaker just is installed in this chamber.The roof of circuit breaker chamber 9 is insulating barriers 8, innovative point of the present utility model is: from lower to upper, begin a pressure release passage 1 to be set from circuit breaker chamber 9 to the switch cabinet top, at first some through holes are set in the part of insulating barrier 8, then by pressure release passage wall 2,3,4,5,6,7 with all through holes, surround a passage and become pressure release passage 1.The outlet of pressure release passage 1 is located on the roof of cabinet, and the exit is topped with the cover plate of a paliform, for example adopts shutter.
Cover plate can adopt radial type with being connected of cabinet roof, flies out under the impact of pressure gas to prevent cover plate, and has an accident.Also can adopt a side to fix with metal bolts, the bolt location that opposite side is made with nylon material, when circuit breaker breaks down, when cover plate was impacted, nylon bolt at first ruptured, and cover plate is turned over to the metal bolts side, had prevented flying out of cover plate.
Claims (2)
1. switch cubicle structure, comprise circuit breaker chamber (9), it is characterized in that: on the local location of the insulating barrier (8) at described circuit breaker chamber (9) top, be provided with a plurality of through holes, the through hole top is provided with a pressure release passage, the outlet of pressure release passage is located on the roof of cabinet, has the fence type cover plate that a radial type connects in the outlet.
2. switch cubicle structure as claimed in claim 1 is characterized in that: a side of described cover plate is fixed by metal fastenings, and opposite side is located by nylon fasteners.
