Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as Figure 1-2 As shown, the assembly structure of the two-hand car busbar chamber of the high-voltage switchgear includes the upper PT handcart 1, the upper static contact 2, the lower PT handcart 4 and the lower static contact 5, and the upper static contact 2 passes through the upper PT handcart The vehicle contact row 3 is connected to the branch busbar 7; the lower static contact 5 is connected to the branch busbar 7 through the lower PT handcart contact row 6; the branch busbar 7 is connected to the main busbar. The branch busbar 7 is connected to the cable room from the main busbar, and then connected to the branch busbar 7 through the upper and lower PT handcart contact rows 3 and 6, and the upper and lower PT handcart contact rows 3 and 6 To connect the busbar, it also plays the role of supporting and fixing the branch bu...

Abstract

The invention relates to an assembly structure of a high-voltage switch cabinet dual-handcart busbar compartment. The assembly structure comprises an upper PT handcart, an upper fixed contact, a lowerPT handcart and a lower fixed contact, the upper fixed contact is connected with a branch busbar through the upper PT handcart contact bar; the lower fixed contact is connected with the branch busbarthrough a lower PT handcart contact bar; and the branch busbar is connected with a main busbar. The busbar compartment assembly and the grounding bar assembly are safe and reliable to achieve five-prevention requirements, save the copper bars and reduce the production cost.

Description

technical field [0001] The invention relates to an assembly structure of a high-voltage switch cabinet, and specifically discloses an assembly structure of a double-hand car busbar chamber of a high-voltage switch cabinet. Background technique [0002] In the high-voltage switchgear, according to the design requirements of the design institute, some switchgears should be designed as a double-handed car structure. The switchgear form of the double-handed car: some have PT handcarts on the upper and lower sides, and some have isolated PT handcarts on the upper and lower sides. There are also circuit breakers on the top and PT handcarts on the bottom; [0003] The grounding method of the circuit breaker handcart is realized through frictional grounding in the middle of the chassis of the circuit breaker, thus ensuring the safety and reliability of the circuit breaker handcart and the entire system. And the switchgear of two-handed car just can't use this mode of frictional gro...
