Abstract

The invention provides an engagement depth measuring method of a contact engagement rack for a handcart type breaker. The engagement depth measuring method includes the following steps: fixing a moving contact of the handcart type breaker on a moving-contact mounting and adjusting plate by a fastener; fixing a fixed contact of the handcart type breaker on a fixed-contact mounting and transferring flange; adjusting front and back positions for mounting of a support base and adjusting up and down positions for mounting of the moving contact to enable the axis of the moving contact to be aligned to the axis of the fixed contact; rotating a hand wheel anticlockwise, and driving the fixed contact to move toward the direction away from the moving contact by a screw rod to separate the fixed contact from the moving contact to a proper position; mounting a measuring device; rotating the hand wheel clockwise, and driving the fixed contact to move toward the direction close to the moving contact by the screw rod to realize engagement of the fixed contact and the moving contact; rotating the hand wheel anticlockwise, and driving the fixed contact to move toward the direction away from the moving contact by the screw rod to realize separation of the moving contact and the fixed contact. By the engagement depth measuring method, developing and measuring efficiency of instruments such as contact engagement depth measuring devices for handcart type breakers of highly-closed armoured high-voltage switch cabinets can be improved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a method for testing the engagement depth of a handcart type circuit breaker contact engagement bench. Background technique [0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is used as electrical products with a voltage level of 3.6kV ~ 550kV, and high-voltage isolating switches And grounding switch, high-voltage load switch, high-voltage automatic recloser and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear and other major categories. [0003] The high-voltage switchgear has the functions of overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. It is mainly used in various places such as power plants, ...
