Description
Technical field
The invention belongs to high-tension apparatus technical field, and in particular to a kind of indoor armor fixing type metal closing switch sets
It is standby.
Background technology
Existing switch cubicle exists bulky, and complex structure, degree of protection are low, and operation interlocking is complicated and unreliable etc. asks
Topic, existing handcart switch cabinet are typically installed using middle, such as KYN28 intermediate switchgear cabinets, its primary cut-out for using
Three-phase major loop lateral arrangement, is operated by breaker bottom chassis car, can be pushed ahead breaker, reaches operating position
When, major loop realizes conducting by dynamic/static contact grafting；Which has the disadvantage that primary cut-out three-phase major loop lateral arrangement causes cabinet
It is wide larger, and handcart moves forward and backward the certain stroke of needs, so as to cause cabinet deep relatively deep, therefore floor space is very big；In addition thereon
Lower three pairs of contact boxs are located in the middle part of switch cubicle, closely, and apart from little, the class of insulation is low, such as upper and lower contact box conducting position
