Combined device for contactless type measurement through electrical testing equipment and application thereof

Abstract

The invention provides a combined device for contactless type measurement through electrical testing equipment and an application thereof. The combined device for the contactless type measurement is used for digitally collecting power equipment signals and further wirelessly transmitting the power equipment signals to the electrical testing equipment, and comprises one control host and multiple detection terminals, wherein the control host and the multiple detection terminals form a star network through the remote communication of a radio frequency module, so that the point-to-multipoint combined measurement device is formed; one end of the combined measurement device is connected with power equipment through the detection terminals; the other end of the combined measurement device is connected with the electrical testing equipment through the control host; and modules of the detection terminals are connected with the power equipment, so that the corresponding electrical test measurement is performed on the power equipment. Based on a contactless type sensing technique and a radio frequency technique, the device adopts a contactless type sensor technique to replace the traditional measurement way; through a networking technique, the digital collection and the transmission are realized; as the procedures of measurement, collection and the like are effectively separated, the working of workers in the risky areas is prevented; and therefore, the working efficiency is improved and the operation risk is lowered.

Description

technical field [0001] The present invention relates to the maintenance and test of electric equipment in electric power system, especially relates to the electric test of high-voltage equipment, especially relates to the combination device and its application of using electric test equipment to carry out non-contact measurement on electric equipment. Background technique [0002] A large number of electrical tests are required during the operation of power equipment. Electrical tests are an important part of the technical supervision of power transmission and transformation equipment. A large amount of electrical test work is involved in the operation test, handover test or fault diagnosis, and the electrical test has become an important part of the power system work. [0003] At present, contact measurement or non-contact measurement for a single device is widely used in electrical tests. For test items that need to collect secondary terminal signals, most of them use co...

AI Technical Summary

Problems solved by technology

For test items that need to collect secondary terminal signals, most of them use contact measurement, which has a high risk of operation and a certain loss to the equipment. For test equipment that integrates pressurization and operation, the safety risk of operators is relatively high. Both require a lot of wiring and are prone to misconnection

Accidents often occur in electrical tests due to mis-disassembly, mis-connection of secondary lines, and insufficient safety distance from pressurized equipment
