Embodiment 1

[0027] This embodiment is basically as figure 1 As shown: the temperature measurement and alarm device for electrical equipment, including an alarm unit, a temperature control unit, a controller and a temperature tester. The temperature tester is installed in the electrical equipment 10 for detecting the temperature inside the electrical equipment 10 . In this embodiment, the controller used is the model MAM-280A controller of Shenzhen Plot Electronics Co., Ltd.

[0028] The temperature control unit includes a power mechanism, an intermediate cylinder 40 and a liquid nitrogen tank 20 , and both the intermediate cylinder 40 and the liquid nitrogen tank 20 are fixedly installed on the casing of the electrical equipment 10 . The liquid nitrogen tank 20 is connected with a connecting pipe 21, and a solenoid valve 22 is installed on the connecting pipe 21; one end of the connecting pipe 21 communicates with the shell of the electrical equipment 10, and the electrical equipment 10 i...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that the alarm unit of this solution is a buzzer, and the buzzer is electrically connected to the controller. After the temperature tester transmits the abnormal temperature signal to the controller, the controller makes the buzzer sound to remind the workers to check the situation of the electrical equipment 10 as soon as possible.

Embodiment 3

[0037] Such as figure 2 As shown, the temperature measurement and alarm device for electrical equipment includes an alarm unit, a temperature control unit, a controller and a temperature tester. The temperature tester is installed in the electrical equipment 10 for detecting the temperature inside the electrical equipment 10 .

[0038] The temperature control unit includes a power mechanism, an intermediate cylinder 40 and a liquid nitrogen tank 20 , and both the intermediate cylinder 40 and the liquid nitrogen tank 20 are fixedly installed on the casing of the electrical equipment 10 . The liquid nitrogen tank 20 is connected with a connecting pipe 21, and a solenoid valve 22 is installed on the connecting pipe 21; one end of the connecting pipe 21 communicates with the shell of the electrical equipment 10, and the electrical equipment 10 is provided with a nozzle pipe 23 communicated with the connecting pipe 21, The nozzle pipe 23 is connected with multiple spray columns. ...

Abstract

The invention belongs to the technical field of warning devices for electrical equipment, and specifically relates to a temperature measurement and alarm device for electrical equipment, including an alarm unit, a temperature control unit, a controller and a temperature tester; the temperature control unit includes a power mechanism, an intermediate cylinder and a liquid nitrogen tank, A connecting pipe is connected to the liquid nitrogen tank, and a solenoid valve is arranged on the connecting pipe; two wiring rods are arranged in the middle cylinder, and a wire is connected between the wiring rod and the solenoid valve, and the first power supply is connected to the wire; the slide in the middle cylinder Connected with a piston; the piston is provided with a conductive guide that can connect two terminal rods, and the power mechanism drives the piston to slide to one side of the terminal rod; the middle cylinder is connected with an air inlet pipe that communicates with the electrical equipment shell; the power mechanism and temperature test The instrument is connected with the controller in communication. In this solution, when the internal temperature of the electrical equipment is too high, the electrical equipment will not stop working immediately, but the temperature will be lowered first to avoid the electrical equipment continuing to work and causing the components to burn out.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment warning devices, and in particular relates to a temperature measurement and alarm device for electrical equipment. Background technique [0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. The important role played by electricity in our life and production cannot be ignored. It brings us great convenience and becomes an important energy source in our production and life. The most critical factor for the normal operation and transmission of electricity in a power plant is the electrical equipment. In order to ensure normal power supply, it is of great significance to ensure the stable operation of electrical equipment. [0003] Electrical equipment generates a lot of heat during operation. In order to avoid excessive temperature, a heat dissipation structure is usually set up to dissipate h...
