Abstract

The invention discloses a wireless sensor device applied in detection of a high pressure oil-immersed current transformer; the wireless sensor device comprises a temperature sensor, a pressure sensor,a signal processing unit, a sensor main control unit and a wireless transmit-receive module; the temperature sensor and the pressure sensor are respectively connected with the signal processing unit;the signal processing unit is connected with the sensor main control unit; the sensor main control unit is connected with the wireless transmit-receive module. The invention also provides a wirelessdetection system. The wireless sensor device and wireless detection system can detect the temperature and pressure values in the high pressure oil-immersed current transformer, and send the information to a server via the wireless transmit-receive module, thus real time detecting whether the high pressure oil-immersed current transformer has oil insufficient and breakdown accidents or not, and preventing untimely inspection of personnel and manpower wasting problems.

Description

technical field [0001] The invention relates to the technical field of high-voltage electrical equipment, in particular to a wireless sensing device and a wireless detection system applied to high-voltage oil-immersed current transformers. Background technique [0002] High-voltage oil-immersed current transformers use oil to insulate the coils. During the operation of high-voltage equipment, internal breakdown often occurs for some reason and a large amount of gas is generated, resulting in an increase in internal pressure and even an explosion. At present, the explosion-proof method of high-voltage oil-immersed current transformer is to install a metal expander. When the transformer fails, the gas generated will increase the internal pressure and make the metal expander stretch to release the pressure and indicate the fault. Or install an explosion-proof device on the oil-immersed current transformer, and vent the explosion when the pressure reaches a certain value. Regar...
