Handcart switch cabinet lower grounding handcart and method

Abstract

The invention provides a handcart switch cabinet lower grounding handcart. The handcart switch cabinet lower grounding handcart comprises a frame, a chassis vehicle connected with the frame, an operating mechanism and a grounding detection device, wherein the grounding detection device comprises a circuit breaker, a grounding bar, a contact and a contact arm, one end of the contact arm is connected with the sensor, and the other end is connected with the contact; the contact is connected with the grounding bar through the circuit breaker; the operating mechanism is connected with the circuit breaker and used for controlling switching-on and switching-off actions of the circuit breaker; and the chassis vehicle is mounted at the bottom part of the frame and used for adjusting the position ofthe grounding handcart. Therefore, the requirement of grounding at two ends of a working place during single-interval maintenance of a 10 kV switch cabinet is met, and the personal safety of maintenance personnel is guaranteed; and the grounding handcart is provided with a sensor and the circuit breaker, thereby preventing the grounding handcart from being mistakenly connected to a live line, andguaranteeing the personal safety of power grid equipment and operation and maintenance personnel.

Description

technical field [0001] The present disclosure relates to a grounding handcart under a handcart switch cabinet and a method thereof. Background technique [0002] The existing grounding handcart is a busbar grounding handcart, which is mainly suitable for the maintenance of the entire section of the 10kV switchgear, and it does not have the function of electric inspection. During the single-interval maintenance of the 10kV switchgear, only the ground knife on the line side can be closed, which cannot meet the requirements of the two working places. The requirements for hanging the ground wire at the end. [0003] At present, there is a problem that the grounding wire cannot be hung at the isolation place under the handcart switch cabinet during single-interval maintenance of the 10kV switchgear, which cannot meet the requirements of hanging the grounding wire at both ends of the workplace, and the current handcart is often mistakenly connected to the grounding handcart when o...

Requirements for end-mounted ground wires

[0003] At present, there is a problem that the grounding wire cannot be hung at the isolation place under the handcart switch cabinet during single-interval maintenance of the 10kV switchgear, which cannot meet the requirements of hanging the grounding wire at both ends of the workplace, and the current handcart is often mistakenly connected to the grounding handcart when operating the handcart. How to avoid mistakenly connecting the grounding handcart to the live interval is a technical problem that needs to be solved
