Visualized test rack for contact engagement of handcart type breaker

Abstract

The invention provides a visualized test rack for contact engagement of a handcart type breaker, and belongs to the technical field of machinery. The test rack comprises a visualized shell, a rack, a moving-contact mounting and adjusting plate, a moving contact, a fixed contact, a fixed-contact mounting and transferring flange, a support base, a screw rod and double-nut assembly and a hand wheel. The moving-contact mounting and adjusting plate is mounted on the inner side of the left end of the rack, and is used for adjusting a mounting position of the moving contact. The screw rod and double-nut assembly is mounted at the right end of the rack in a sleeved manner. The hand wheel is mounted at the right end of the screw rod and double-nut assembly. The fixed-contact mounting and transferring flange is mounted at the left end of the screw rod and double-nut assembly, and is used for connecting the fixed contact with the screw rod and double-nut assembly. The visualized shell is mounted on the periphery of the rack. By the test rack, the problems such as tedious adjustment, frequent movement and manpower and material resource waste of instruments such as contact engagement depth measuring devices for handcart type breakers of closed armoured high-voltage switch cabinets are solved, and device production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a handcart type circuit breaker contact engagement visualization test 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 functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. It is mainly applicable to various fields such as power plants, substations, petro...

AI Technical Summary

Problems solved by technology

However, during the design and manufacturing process of the instrument, in order to adjust the fixed installation scheme of the displacement sensor, it is necessary to frequently go to the installation site of the high-voltage switchgear, and the start and stop of the switchgear also affects the normal power supply, which is troublesome and wastes manpower and material resources
