Cage rolling type spark gap zero detection device

Abstract

The invention relates to a spark gap zero detection device, in particular to a cage rolling type spark gap zero detection device. The cage rolling type spark gap zero detection device is characterized by comprising a bracket and cage rotors, wherein the bracket consists of a horizontal edge and two vertical edges fixed at both sides of the horizontal edge; and the cage rotors are fixed inside the two vertical edges of the bracket through a rotating shaft. The cage rolling type spark gap zero detection device has a simple structure and is convenient and efficient to use. The defects of the existing spark gap zero detection device are overcome. In the measuring process, a triangular stable structure is formed by taking a human body as a supporting point; and an operator does not need to carry out lift-up and put-down operation and only needs to drag an operating rod to ensure the rotors to carry out rotational measurement, so that the measuring time is greatly shortened and the labor intensity of the operator is reduced. Meanwhile, the number of spark gaps is effectively reduced, so that the measurement is more accurate and the measurement error is reduced.

Description

technical field [0001] The invention relates to a spark gap zero measuring device, in particular to a cage rolling type spark gap zero measuring device. Background technique [0002] Zero-value insulator detection is a very important task in the live work of power lines. The spark gap zero-measuring device is a zero-measuring tool commonly used by power supply companies at the present stage. It has the advantages of simple structure, light weight and durability, but it has the following problems: 1. When using the method of ground potential to measure zero, the spark gap is installed on the top of the insulating operating rod of the corresponding voltage level. The operator needs to use the body as the fulcrum and hold the tail of the operating rod to lift and lower the operation. It is a laborious lever. structure, the labor intensity of the operator is relatively high, and it takes a long time, which is prone to danger. 2. The metal probe in contact with the insulator of ...

2. The metal probe in contact with the insulator of the ordinary spark gap zero measuring device is prone to deformation, and the working head is easy to rotate around the insulating rod as the axis. The measurement position cannot be fixed each time, and measurement errors are prone to occur; 3. Ordinary spark gap zero measurement The device can only be used when the power line is running. When the power line is out of power for maintenance, the zero measurement experiment cannot be carried out, which has certain limitations.
