Description
Technical field
The utility model belongs to electric equipment technical field, is specifically related to a kind of pressure relief device of switch cabinet of ventilation and heat.
Background technology
Switch cubicle is in running, because of various reasons, as short circuit, ageing of insulation, human operational error etc., cause primary circuit short trouble to occur, under the short circuit current of tens thousand of amperes, moment produces high temperature and high pressure gas, if high temperature and high pressure gas can not effectively discharge in narrow cabinet within the utmost point short time, can cause switch cubicle to burst, adjacent switch cabinet damages, and may injure personal safety simultaneously.Therefore, switch cubicle, in the time of design, must be considered effective pressure-relief measure.Existing switch cubicle is only being done consideration aspect pressure release and protection, and pressure relief device complex structure, and pressure release effect is bad, simultaneously the also extreme difference of radiating effect of cabinet.
Utility model content
The purpose of this utility model is: for above-mentioned electric equipment exist problem, a kind of pressure relief device of switch cabinet of ventilation and heat is provided, can effectively solve pressure release problem, there is good result of ventilating heat dissipation simultaneously.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of pressure relief device of switch cabinet of ventilation and heat, comprise the pressure release passage being arranged on the mounting rail of switch cubicle top, described pressure release passage comprises supporting frame, removable cover, supporting frame is fixed on mounting rail, removable cover one lateral edges is fixedly connected with supporting frame by screw, and be provided with the turn-line for removable cover upset in inner side, edge, on the supporting frame of removable cover opposite side, be provided with compressing tablet, removable cover is stuck in movable compressing tablet lower end; The two sides of supporting frame are provided with the Dense mesh screen plate with ventilation and heat.
Preferably, be provided with interior turnover panel in supporting frame two inner sides with Dense mesh screen plate, interior turnover panel one end and supporting frame are fixed, and are also provided with turn-line in stiff end inner side.
Preferably, described pressure release passage arranges three, is followed successively by breaker chamber pressure release passage, bus-bar room pressure release passage, cable vault's pressure release passage.
Preferably, described removable cover and the supporting frame surrounding horizontal cornice of formation that stretch out respectively.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
The pressure relief device of switch cabinet of a kind of ventilation and heat of the present utility model, meets pressure release, requirement of shelter, heat dissipation problem while simultaneously also considering equipment operation, and simple in structure; In pressure relief device, be provided with interior turnover panel, when pressure release, interior turnover panel blocks upset, blocks Dense mesh screen plate, thereby blocks lateral airflow simultaneously, guarantees that equipment left and right sides object is unaffected; Removable cover and supporting frame periphery are designed with horizontal cornice, prevent from having the material access arrangement of a fixed inclination direction.
