Telescopic mistaken touch prevention isolation tool for secondary terminal strip

Abstract

The invention discloses a telescopic mistaken touch prevention isolation tool for a secondary terminal strip, and belongs to an isolation tool used for field operation in a regular inspection test ofsecondary equipment in the power industry. The isolation tool comprises a warning isolation belt, and telescopic isolation assemblies are installed at the top and the bottom of the warning isolation belt respectively. The telescopic isolation assemblies can stretch out and draw back in the height direction of the warning isolation belt, and a fixing device is further installed on each telescopic isolation assembly. The fixing devices can be detachably installed on a secondary terminal strip, and the warning isolation strip, the telescopic isolation assembly and the fixing devices are all madeof insulating materials. The invention aims to solve the problems that secondary terminal still exists in the same screen during regular check test of the current protection, measurement and control devices, the operation risks of mistaken contact, mistaken touch and mistaken disconnection and connection exist, and the potential safety hazard of power grid load loss caused by misoperation of the device exists.

Description

technical field [0001] The invention relates to an isolation tool used for on-site operation during the regular inspection and test of secondary equipment in the electric power industry, in particular to a retractable secondary terminal row anti-mistouch isolation tool. Background technique [0002] With the rapid development of the power industry, there are a large number of secondary screen cabinets in substations. There are multiple secondary equipment with different intervals and multi-section terminal blocks in the same screen cabinet. During the transformation, the staff only need to work on some terminal blocks inside the screen cabinet, and the metal connecting members of the secondary terminal blocks at other intervals in the same screen are exposed. If the staff accidentally touches, disconnects the wires by mistake or unwraps the terminals during the work process, it will not work. Strictness will cause the circuit to be short-circuited, which will prompt the prot...
