Abstract

The invention discloses a high-voltage brake pull-rod capable of measuring the temperature and the load current. The high-voltage brake pull-rod capable of measuring the temperature and the load current comprises a brake pull-rod body and a link hook, and further comprises a temperature sensor and a current transformer which are arranged on the brake pull-rod. The magnetic core of the current transformer is composed of a magnetic core upper portion and a magnetic core lower portion. The signal output end of the current transformer and the signal output end of the temperature sensor are respectively connected with a signal processing switching circuit. A display module is connected to the output end of the signal processing switching circuit. The lower end of the magnetic core is fixed on the brake pull-rod, the upper end of the magnetic core is provided with a magnetic core rotating shaft and a drawing wire fixing hole, the upper portion of the magnetic core can rotate around the magnetic core rotating shaft, a spring fixing hole in a spring is formed in the magnetic core rotating shaft, and a drawing wire is connected with a drawing wire operation button through the drawing wire fixing hole. The high-voltage brake pull-rod capable of measuring the temperature and the load current avoids insulation breakdowns caused by high-voltage measurement or human body security threat possibly caused by measurement in special weather, ensures personal safety in the operation process, and avoids human body electric shock accidents.

Description

technical field [0001] The invention relates to an electric power equipment operation tool, in particular to a high-voltage electric rod capable of measuring temperature and load current. Background technique [0002] At present, the high-voltage insulation gram rod is a common operating tool in the power industry, and it is an indispensable tool for the operation of 10~35KV line high-voltage gram in the power production process. Although the gram rod has undergone some continuous improvements, it still has shortcomings. place. The lead wire of the measurement circuit is connected to the operating position of the handle, which is relatively close to the human hand, and there are certain safety hazards. When measuring the line current, when actually measuring the 10~35KV line current, the induced voltage increases due to insulation and special weather. Once If the induced voltage exceeds the specified value, it will cause personal damage and even endanger the safety of the o...
