Abstract

The present invention relates to a kind of base pressure switch cubicle arc-control device, door body including the door frame being arranged in the side wall of base pressure switch cubicle and on door frame, the door body is hinged with door frame, the hinged place of the door body and door frame, which is provided with, is used for the torsion spring that door body resets, the base pressure switch cubicle is provided with travel switch and relay, when in use, travel switch is can trigger when the door body is opened so as to drive relay to disconnect bus current.The device can quickly isolate to arc fault.

Description

Base pressure switch cubicle arc-control device
Technical field
The present invention relates to a kind of base pressure switch cubicle arc-control device, belong to electrical equipment technical field.
Background technology
Fault electric arc is a kind of random physical phenomenon that mathematical statistics method can be used to describe, and this phenomenon is also referred to as gas Volume ionization.This gas ionization is air ionization first, and passes through (phase and phase, phase and ground between) between different potentials, electrode High-temperature electric conduction plasma gas remains.If fault electric arc being regarded as to, in electricity grid network if a kind of element, then it is one Non-linear ohm component that kind changes over time.
When arc fault occurs for low-tension switch cabinet, strong arc light is seen first, with this coral as low-voltage cabinet is emerged dense Dense black smoke and strong explosive sound.Always highest field strength position forms arc root on bus during fault electric arc short circuit.So When arc fault occurs in a certain position of cabinet, electric arc is migrated along bus bar edges, and electric arc may be trapped on the angle of bus Stable burning, cause dissolving and vaporizing for metal material.
Due to break down electric arc when pressure, radiation, arc root effect cause equipment seriously to damage, while high temperature, high pressure Gas produces red-hot metal with electrical arcing and nonmetallic materials particle is escaped by cabinet, causes personal injury, or even draw Play fire.Therefore, it is exactly the problem of people are currently in the urgent need to address to arc fault Protective Research.
The content of the invention
The invention solves technical problem to be:The shortcomings that overcoming above-mentioned technology, there is provided one kind is simple in construction and can be to electricity The base pressure switch cubicle arc-control device that arc failure is quickly isolated.
In order to solve the above-mentioned technical problem, technical scheme proposed by the present invention is:A kind of base pressure switch cubicle arc-control device, bag Include and be arranged on the door frame in the side wall of base pressure switch cubicle and the door body on door frame, the door body is cut with scissors with door frame Connect, the hinged place of the door body and door frame, which is provided with, is used for the torsion spring that door body resets, and the base pressure switch cubicle is opened provided with stroke Pass and relay, travel switch is can trigger when in use, when the door body is opened so as to drive relay to disconnect bus current.
The present invention is so produced by setting door body structure in the side wall of base pressure switch cubicle when breaking down arc short circuit Under raw high-tension current impact, door body, which rotates, acts travel switch, drives relay striping bus, so as to be carried out to bus Strengthen protection.Protection switch cabinet can thus be played a part of, then door body Rapid reset in the presence of torsion spring, so as to anti- Only red-hot metal is produced in base pressure switch cubicle with electrical arcing and nonmetallic materials particle is escaped by cabinet, cause personal wound Evil triggers or causes fire.
Preferably, the door frame and door body, which are adopted, is made from an insulative material.
The further improvement of above-mentioned technical proposal is:The door frame is provided with two and carries the upper and lower prominent of vertical through hole Platform, the top of the door body are provided with the pin that can be inserted into upper convex through hole, and the bottom of the door body is provided with counterbore and and counterbore The hinge being spirally connected, the through hole of the hinge through lower convex are inserted into counterbore.Because being easily damaged in the presence of electric arc, this Sample can easily be dismantled by screwing off pin, change door body.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the schematic diagram of door frame in the embodiment of the present invention.
Fig. 3 is the schematic diagram of door body in the embodiment of the present invention.
Embodiment
The base pressure switch cubicle arc-control device of the present embodiment, as shown in figure 1, including being arranged in the side wall of base pressure switch cubicle Door frame 1 and the door body 2 on door frame 1, the door body 2 is be hinged with door frame 1, the door body 2 and door frame 1 Hinged place, which is provided with, is used for the torsion spring that door body 2 resets, and the base pressure switch cubicle is provided with travel switch and relay, used When, travel switch is can trigger when the door body is opened so as to drive relay to disconnect bus current.The door frame 1 and door body 2 It is made from an insulative material it is preferred that adopting.
As shown in Figures 2 and 3, door body is changed for convenience, and door frame 1 described in the present embodiment is provided with two with perpendicular The upper and lower convex 3,4 of clear opening, the top of the door body 2 are provided with the pin 6 that can be inserted into the upper through hole of convex 3, the body of door 2 Bottom is provided with counterbore and the hinge 5 being spirally connected with counterbore, and the through hole of the hinge 5 through lower convex is inserted into counterbore.Because It is easily damaged in the presence of electric arc, so can be easily dismantled by screwing off pin, change door body.
The present invention is not limited to the concrete technical scheme described in above-described embodiment, and in addition to the implementation, the present invention may be used also To there is other embodiment.All technical schemes formed using equivalent substitution, it is the protection domain of application claims.
