Problems solved by technology

[0004] The disadvantage is that the horizontal layout of the three-phase main circuit of the high-voltage circuit breaker results in a large cabinet width, and the handcart needs a certain stroke to move forward and backward, resulting in a deep cabinet depth, so it occupies a large area; Large, high processing cost, and used as the main heat source, causing energy loss and affecting the safety of equipment work

Abstract

The invention relates to a longitudinal movable-type circuit breaker centrally installed switchgear, a circuit breaker truck can be longitudinally pushed or pulled from a circuit breaker chamber is realized through arranging a busbar chamber, the circuit breaker chamber and a cable chamber from top to bottom; an upper disconnecting switch moving contact and a lower disconnecting switch moving contact which are synchronously driven by a link mechanism are arranged on the circuit breaker truck relative to each fixed contact seat group; the upper disconnecting switch moving contact and the lower disconnecting switch moving contact move in reverse direction through driving the link mechanism to respectively insert to an upper fixed contact seat in the busbar chamber and a lower fixed contact seat in the cable chamber, then an upper disconnecting knife and a lower disconnecting knife are synchronously closed; and truck circuit breaker closing operation is performed finally, and power transmission is completed.

Description

Technical field [0001] The invention belongs to the technical field of electrical equipment, and specifically relates to a longitudinally removable type circuit breaker central cabinet. Background technique [0002] The A, B, and C three-phase contacts of the current removable switchgear generally adopt a horizontal and central arrangement. It is defined that the three-phase contacts of the circuit breaker A, B, and C are arranged longitudinally along the rear, middle, and front directions relative to the operator. , The three-phase contacts of circuit breaker A, B, C are arranged horizontally along the left, center and right directions. [0003] For example, KYN28 middle-mounted switchgear, the three-phase main circuit of the high-voltage circuit breaker used in it is arranged horizontally and linearly on the left, middle and right. The circuit breaker can be pushed forward and backward (ie longitudinally) through the operation of the bottom chassis of the circuit breaker. , When...
