Cart for operating high-voltage switch cabinet handcart

Abstract

The invention discloses a cart for operating a high-voltage switch cabinet handcart. The cart comprises a base, wherein the base is provided with a transverse rotating shaft and a longitudinal rotating shaft vertical to the transverse rotating shaft; the transverse rotating shaft protrudes towards the front side of the base; a handle for driving the longitudinal rotating shaft to rotate is arranged at the upper end of the longitudinal rotating shaft; the lower end of the longitudinal rotating shaft and the rear end of the transverse rotating shaft are in matched connection through a gear bank, so that the longitudinal rotating shaft drives the transverse rotating shaft to rotate while rotating; the front part of the transverse rotating shaft is movably connected with a sleeve matched with a rotating shaft of the high-voltage switch cabinet handcart and the sleeve can drive the rotating shaft of the high-voltage switch cabinet handcart to rotate; and a height adjusting plate is arranged at the lower part of the base and is provided with a height adjusting device for adjusting the height of the base. According to the cart, the rotating shaft of the high-voltage switch cabinet handcart can be driven to rotate through the sleeve, standing operation can be carried out, and the cart disclosed by the invention can adapt to the high-voltage switch cabinet handcarts with different heights and environments.

Description

technical field [0001] The invention relates to electric equipment, in particular to an operating device for a handcart of a high-voltage switch cabinet. Background technique [0002] KYN28A-12 is a relatively common high-voltage switchgear in China. Its full name is: indoor metal armored removable switchgear. It is suitable for three-phase AC 50Hz power system with a rated voltage of 3.6kV-12kV. And distribute electric energy and participate in the circuit to implement control, protection and monitoring. Its characteristic is that the equipped vacuum circuit breaker is a central type, that is, the circuit breaker is located in the middle of the front cabinet of the switch cabinet, so the lower space can be used for expansion of other schemes or as a cable room. [0003] At present, in the handcart-type high-voltage switchgear, the switching of the switch handcart between the working position and the test position is realized by the operating handle. Using this operating ha...

Problems solved by technology

[0003] At present, in the handcart-type high-voltage switchgear, the switching of the switch handcart between the working position and the test position is realized through the operating handle. Using this kind of operating handle to operate the switch handcart is inconvenient to use and has great potential safety hazards.

Due to the design problem of the switchgear, the operating position of the arrester trolley is too low, so that when operating the arrester trolley, the operating handle cannot be rotated 360° and the operator cannot operate upright, making the operation difficult
