Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.Disclosed in this utility model it is
A kind of KYN-40.5kV high-tension switch cabinet, as it is shown in figure 1, be preferred embodiment of the present utility model, before in cabinet, cabinet
Upper lateral part is provided with control room 1, and lower front is provided with breaker chamber 2, is provided with for installing main busbar and branch's busbar on the upside of middle part
Bus-bar room 3, rear portion is provided with cable vault 4.
As it is shown in figure 1, separated by dividing plate between each compartment and be provided with independent pressure release passage, it is respectively as follows: chopper
Room 2 pressure release passage A, cable vault 4 pressure release passage B, in order to strengthen the security performance of high-tension switch cabinet.
Being provided with chopper 5 in described breaker chamber 2, chopper 5 uses handcart 6 console model structure；Described bus-bar room 3 side
