Abstract

The invention discloses a wireless digital monitoring sensor for electrical equipment, which consists of a shell, a singlechip circuit, a power supply, a control circuit, a wireless communication circuit, a voltage detection circuit, a current detection circuit, a temperature detection circuit, a clock circuit, a line status detection circuit and an antenna, wherein the singlechip circuit, the power supply and the control circuit are arranged in the shell, and the antenna is arranged outside the shell. According to the device which is a wireless digital monitoring sensor, an electromagnetic field and a sensing component in the same space are utilized, so that the times and detailed time of common power failure and power transmission, the current value, the voltage value and relevant electric parameters with a fuzzy control method, and the common faults, such as large current overrun, interphase short circuit, local temperature rise overrun, strong power intrusion, surge, thunderbolt and the like of a power supply line and power equipment can be simultaneously detected.

Description

technical field [0001] The invention relates to a wireless online detection device for power transmission and transformation lines, which is used for detecting parameters such as current, voltage, temperature rise and cycle deviation in the line, and monitoring the running state of the power line. Background technique [0002] With the rapid development of power construction and the continuous expansion of power grid scale, remote monitoring of transmission lines and related parameters of power equipment has become an important issue that must be solved. In particular, the intelligent multi-functional online monitoring device is an important part of the smart grid and safe power supply links, and is an important technical means to achieve safe operation, maintenance management, and improve production and operation management. Currently, in the prior art, various on-line monitoring devices with a single function have been developed. Typical technical solutions include: (1) I...

AI Technical Summary

Problems solved by technology

Typical technical solutions include: (1) In the Chinese patent (application number: CN200510047898.9), a wireless temperature detection device is proposed, but the device can only detect the local temperature rise parameters of transmission lines and power equipment , but cannot detect other relevant electrical parameters; (2) In the Chinese patent (application number: CN200610123199.2), a wireless charged display locking device is proposed, but the device can only detect whether the transmission line and electric equipment are charged state, but cannot detect other relevant electrical parameters

To sum up, the existing technical solutions lack a comprehensive, multi-functional and intelligent online monitoring device, so they cannot meet the actual on-site operation needs
