Product Introduction

The temperature monitoring points of high-voltage electrical equipment are in the environment of high voltage, high current, and strong magnetic field. Some monitoring points are even in confined spaces. Due to the problems of strong electromagnetic noise, high-voltage insulation, and space limitations, the usual temperature The measurement method cannot solve these problems and cannot be used. The wireless temperature monitoring system independently developed and designed by our company uses radio waves for signal transmission. The sensor is installed on the high-voltage equipment, and there is no electrical connection with the receiving equipment, so the system fundamentally solves the problem that the operating temperature of the high-voltage equipment contact is not easy to monitor online in real time.

The wireless temperature monitoring system developed by Inverion Optoelectronics Technology (Suzhou) Co., Ltd. has extremely high reliability and safety, and is relatively inexpensive. It can be directly installed on every high-voltage switch, bus connector, outdoor switch or transformer. The system is equipped with a standard communication interface and can be operated on the Internet. Through the host computer software, it can record the real-time operating temperature data of the high-voltage equipment. Provide accumulated data for the maintenance of high-voltage equipment, and realize the predictive maintenance of thermal faults of high-voltage equipment.

The main function

The main function Features
basic skills Receive data Receive the temperature uploaded by the wireless temperature sensor and the sensor working voltage
Display Data Color display of the received data, the display effect is more intuitive, the backlight switch is controllable, suitable for a variety of applications
Clock display Real-time clock display, and as a time reference for event recording
parameter settings All parameters are flexibly settable, easy to operate, and data is not lost when power off
Alarm Output When an alarm event occurs, the relay dry contact signal output and buzzer alarm sound prompt
Temperature alarm record Record the temperature, start time and end time of the temperature measurement location where an alarm has occurred. Up to 200 records can be saved. When there are more than 200 records, the oldest record will be automatically overwritten
Password management Using password management method, you must enter a password when setting parameters. The password is divided into user password and system password. Entering the system password can perform more advanced settings.
