Background technology
With the construction energetically of domestic city track traffic, underground railway track traffic turns into the important composition portion of urban transportation
Point.Because the typically laying of underground railway track means of transportation is built in the underground in city, the quality requirement of iron relevant device is more next over the ground
It is higher.The cabinet top top plate of traction direct-current switch cabinet is one of important component in subway direct-current switch cabinet, and effect is increase direct current
The area of dissipation of switch cubicle, strengthens the heat dispersion of direct-current switch cabinet.Cabinet top top plate is important knot in subway direct-current switch cabinet
Structure part.Existing cabinet top top plate uses the flat board for being provided with degree of protection for IP20 holes, is easily impacted by spray arc, no
The exclusion of the free gas produced during beneficial to arcing.Under extreme case, electric substation's frame protection action may be triggered, cause to lead
Draw abnormal electrical power supply interruption.
Utility model content
The purpose of this utility model is defect and deficiency for prior art there is provided a kind of Novel switch cabinet top cover,
It has raised the distance of spray arc, adds area of dissipation, is conducive to the discharge of free gas produced during arcing, accelerates direct current high
The recovery of fast breaker arc-rupturing capacity；Ensure direct-current switch cabinet stabilization, safe operation.
To achieve the above object, the utility model is using following technical scheme：It includes back plate 1, intermediate cap 2, foreboard
3, back plate 1, intermediate cap 2, foreboard 3 are interconnected to form integral head cover, and square opening 11 is evenly arranged with back plate 1, in
Between the top of cover 2 be also evenly arranged with intermediate cap square opening 21, foreboard 3 is arranged on the top of low pressure cell 4 on the right side of power supply switch cabinet
Two bar-shaped troughs 31 are provided with portion, foreboard 3.
Described back plate 1 and foreboard 3 is provided with suspension ring 5 close to two side edges.The purpose of suspension ring 5 is to facilitate power switch
Cabinet overall lifting and transport.
Described intermediate cap 2 is shroud-like structure, and the front and rear sides of intermediate cap 2 are closed plate 22, the left side plate of intermediate cap 2
Square air vent 24 is evenly arranged with 23, the downside of square air vent 24 is provided with outside extension edge 25.Extension edge 25 is used
In the crown center position that intermediate cap 2 is fixedly connected on to power supply switch cabinet.
The utility model is redesigned to cabinet top top plate.Cabinet top top plate both sides after improvement have carried out bending, lift
Height, has perforate in addition to low pressure cell, has raised the distance of spray arc, has added area of dissipation, be conducive to producing during arcing
Free gas discharge, accelerate DC high speed circuit breaker arc-rupturing capacity recovery.Ensure direct-current switch cabinet stabilization, safety fortune
OK.
