Problems solved by technology

Since the charged static contact is exposed in front of the operator, it is difficult to guarantee the personal safety of the operator during the electrical inspection process
In addition, due to the limitation of the structural space in the switch cabinet, it is not easy to operate by directly connecting the ground wire to the main busbar.
At the same time, the grounding vehicle is grounded and another grounding wire is attached, which will also bring a lot of inconvenience to the grounding operation on site.

Abstract

The invention discloses an electric inspection grounding handcart for a main busbar and a feeder branch. The high-voltage sensor has a live display on the panel, and a grounding interlock mechanism is set on the bracket. The handcart of the circuit breaker integrates the functions of electricity inspection and grounding, and is practical and convenient to operate; a three-phase live display is installed on the handcart panel, and the power and no power can be observed intuitively; there is a grounding interlock between the grounding switch and the handcart rollers. When the grounding switch is in the closed position, the rollers are stuck, and the switch cabinet cannot be pushed forward, which meets the five-proof requirements of machinery. It is suitable for power inspection and grounding of the main bus bar end and feeder branch end of the switch cabinet.

Description

technical field [0001] The invention relates to a handcart device on an electric switch cabinet, in particular to a handcart for electric inspection and grounding of main busbars and feeder branches. Background technique [0002] During the overhaul and maintenance of the switchgear, it is necessary to test and ground the incoming and outgoing lines and the main busbar to ensure the personal safety of the overhaul personnel. In the past, the methods of electric test with electric probe and grounding wire were often used. Since the charged static contact is exposed in front of the operator, it is difficult to guarantee the personal safety of the operator during the electric test. In addition, due to the limitation of the structural space in the switchgear, it is not easy to operate by directly connecting the grounding wire to the main busbar. At the same time, if the grounding vehicle is grounded and another grounding wire is connected, it will also bring a lot of inconveni...
