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 upper incoming line electricity checking and grounding handcart. The upper incoming line electricity checking and grounding handcart comprises a chassis, a roller below the chassis, a support and a panel on the chassis, an electricity checking contact arm and a high-voltage sensor fixed on the support, a live display on the panel, and a grounding interlock mechanism arranged on the support. The handcart has the integrated function of electricity checking and grounding function, and is practical and convenient in operation. The three-phase live display is mounted on the panel of the handcart to facilitate the direct observation of live or non-live state. The grounding interlock is arranged between a grounding switch and the roller of the handcart, and the roller is locked when the grounding switch is in the close position, so that the handcart can not be pushed into a switch cabinet, thereby meeting the requirement for mechanical five preventions. The handcart provided by the invention is suitable for electricity checking and grounding of the upper incoming line terminal 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 upper incoming lines. Background technique [0002] During the inspection 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 maintenance 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 inconvenience to...
