Portable lead wire device

Abstract

The present invention discloses a portable lead wire device. The portable lead wire device mainly comprises a control head, a replaceable head insulation operating lever and a switch handle. The control head is connected with the replaceable head insulation operating lever via a lateral bracing piece through an adjustable elbow joint controlled by a nut twisted by hands; the switch handle is installed at the lower portion of the replaceable head insulation operating lever, and the switch handle is connected with a control cord; and the control cord is connected with the control head and controls the control head through a work post on the lateral bracing piece. A mode of employing the switch handle to control a wiring clamp is employed to change a test wiring mode from 'high-structure vehicle manual wiring' to 'mechanical automatic wiring'. Therefore, the portable lead wire device is convenient and automatic, is universal in test devices, and basically solves problems of upper portionsof primary devices such as a main transformer, a switch, a current transformer, a voltage transformer and the like in the test. The portable lead wire device is popularized and applied to improve safety conditions and technology conditions of field work, shorten power failure time and improve work safety and power supply reliability.

Description

technical field [0001] The invention belongs to the technical field of high-voltage testing, and in particular relates to a portable lead-wire device, which is used for test lead-wires of primary equipment such as transformers, switches, and voltage transformers. Background technique [0002] Due to the large number of main transformer test items, the staff need to change the wiring frequently during the test process, the wiring is highly repetitive and prone to electric shock hazards; at the same time, each test needs to go up and down the transformer bushing more than 20 times, which is labor intensive, especially for 220kV For the main transformer and above, the bushing on the high-voltage side is very high, and an elevated truck is required for wiring. Moreover, regardless of the scorching sun and high temperature in summer and the cold and windy winter, two testers need to change the wiring on the upper part of the transformer for a long time, and the working environmen...

Problems solved by technology

[0002] Due to the large number of main transformer test items, the staff need to frequently change the wiring during the test process, which is highly repetitive and prone to electric shock hazards; at the same time, each test needs to go up and down the transformer bushing more than 20 times, which is labor-intensive, especially for 220kV For the main transformer and above, the bushing on the high-voltage side is very high, and an elevated truck is required for wiring.

Moreover, regardless of the scorching sun and high temperature in summer and the cold and windy winter, two testers need to change the wiring on the upper part of the transformer for a long time, and the working environment is very harsh; one test requires 4 to 5 people, but due to the limited number of team members, if two The main transformer test at or above the platform may easily cause tension in personnel arrangements

Another high-altitude operation of the equipment also faced the situation that the elevated vehicle could not be used
