Adsorption type transformer oil temperature monitoring alarm device and use method

Abstract

The invention provides an adsorption type transformer oil temperature monitoring alarm device and a use method. The adsorption type transformer oil temperature monitoring alarm device comprises a base, a power module, a temperature sensor, a temperature controller, an actuator and a displayer, the power module, the temperature sensor, the temperature controller, the actuator and the displayer are arranged based on the base, the power module is respectively connected with the temperature controller, the actuator and the displayer, and the temperature controller is respectively connected with the temperature sensor, the displayer and the actuator. The temperature sensor comprises a temperature sensing module and can be embedded into the bottom face of the base. The base is a magnetic material part and is adsorbed on the outer surface of a transformer shell. The temperature controller comprises a single-chip microcomputer, an analog-digital conversion chip, a man-machine interface and a data output port, and the analog-digital conversion chip, the man-machine interface and the data output port are respectively connected with the single-chip microcomputer. The device can be applied to various types of transformers, alarm / shutdown temperature can be set according to the running environment, the temperature classification, the oil temperature errors and the transformer by the device itself, the device is simple in structure, low in manufacturing cost and long in service life, temperature is displayed visually and accurately, and the device can be mounted at any time and any where and is the new technology easy to apply and popularize.

Description

technical field [0001] The invention relates to the technical field of transformer oil temperature monitoring and alarming, in particular to an adsorption type transformer oil temperature monitoring and alarming device and a use method thereof. Background technique [0002] In cities and villages, distribution transformers are important power facilities that can be seen everywhere. They are widely used and widely distributed, but there has been a lack of effective supervision measures for a long time. The key to the safe operation of the transformer is that its working temperature should not be too high, otherwise it will damage the insulation of the equipment, accelerate aging, shorten the life span, or even burn out, causing serious accidents such as fire and explosion. One of the difficulties in monitoring the operating temperature of distribution network transformers is that there are many types of transformers, including oil-immersed transformers, amorphous transfor...

Problems solved by technology

[0007] However, the above schemes either need to be configured during the transformer production process, or the temperature measurement function is not specific enough and the application range is not wide enough. For transformers with a capacity below 500KVA, most of them are not equipped with special temperature measurement equipment, and require special inspection by managers. There is no automatic Reminder function, even if an intelligent temperature control instrument is installed, there are disadvantages such as high cost and inconvenient maintenance. Therefore, it is urgent to invent a simple, practical, low-cost, easy-to-install and maintain oil temperature monitoring and alarm device to solve such problems. insufficient
