Monitoring system for overvoltage protector and monitoring method

Abstract

The invention discloses a monitoring system for an overvoltage protector. The monitoring system comprises an MCU, a display module, an alarm device, a data input device, a database, a data comparisonand acquisition device, a data receiving unit, a wireless data transmission module, an inductive device, a voltage sensor, a temperature sensor and a humidity sensor. According to the invention, the inductive device is arranged, so that the pressure relief operation of an overvoltage protector in the invention can be detected immediately, and at this time, whether the overvoltage protector is damaged or not can be easily and accurately detected by comparing a voltage value detected by the voltage sensor and a voltage value within a normal range; the wireless data transmission module communicates with the data receiving unit through GPRS network communication, so that the monitoring device realizes wireless remote monitoring; and the temperature sensor and the humidity sensor are arranged to allow working staff to understand clearly and intuitively whether the damage of the overvoltage protector is due to the service life or external reasons such as temperature and humidity.

Description

technical field [0001] The invention belongs to the field of monitoring and relates to an overvoltage protector, in particular to a monitoring system and a monitoring method for the overvoltage protector. Background technique [0002] The overvoltage protector is an advanced protective device that limits lightning overvoltage and operating overvoltage. The overvoltage protector is a new type of overvoltage protector, mainly used to protect generators, transformers, vacuum switches, busbars, and motors. Insulation of electrical equipment such as from overvoltage damage; [0003] At the moment, there are generally few instruments for the identification and judgment of overvoltage protectors. It is based on past experience to get the approximate number of times an overvoltage protector can be used, and the induction coil induces the overvoltage protector to work.

Problems solved by technology

[0003] At the moment, there are generally few instruments for the identification and judgment of overvoltage protectors. It is based on past experience to get the approximate number of times an overvoltage protector can be used, and the induction coil induces the overvoltage protector to work. After reaching the number of times, it is estimated that it has reached the upper limit of use, otherwise it will be used directly until it fails, but sometimes the overvoltage protector is not necessarily in the normal pressure relief range when it is powered on, which will cause a lot of loss to the electrical appliances. There are not many online monitoring devices for overvoltage protectors in the current stage. The existing online monitoring devices for overvoltage protectors generally transmit data through cables, and there is not enough preparation for the monitoring of overvoltage protectors. , and it is impossible to know the real reason for the damage of the overvoltage protector
