Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] A circuit breaker room modular structure used for transformation of a central cabinet, including a circuit breaker 1, a valve mechanism 2, left and right guide rails 3 and a contact box 4.
[0015] The outside of the left and right guide rails 3 is provided with a valve mounting plate 5, put the contact box 4 into the mounting plate, put the aluminum plate 7 on it, and then use 24 M8*20 inner hexagonal screws (with flat springs) to align the holes. pad) for assembly.
[0016] The contact box mounting plate 6 is equipped with four flat hinges 9, which are aligned with the holes and assembled with ∅8 steel rivets, and the hinge rotation is confirmed to be flexible and reliable. There are left and right side plates on both sides of the modular circuit breaker chamber 8. Fix the valve mounting plate 5 on the left and right side plates 8 with bolts respect...

Description
technical field [0001] The invention relates to the field of power transformation and distribution, in particular to a modular structure of a circuit breaker room used for transformation of a central cabinet. Background technique [0002] With the advancement of technology and manufacturing process, the quality and safety of switchgear have been significantly improved, and the failure rate has been significantly reduced. However, in the harsh physical environment of long-term high voltage and high current, medium and high voltage switchgear will inevitably [0003] The thermal effect cannot be ignored. After long-term operation, the insulating parts in the cabinet are gradually aging, especially in the rainy season, when the ambient humidity is high, it is easy to condense in the switch cabinet, reduce the insulation performance, and easily cause short-circuit accidents. When a short-circuit fault occurs on site, causing the entire cabinet to be burned, it will cause a pow...
