Embodiment 1

[0032] See figure 1 , an internal monitoring system for high-voltage electrical equipment, comprising a box body 1, a plurality of legs 13 are evenly provided at the bottom of the box body 1, and partitions 2 are symmetrically arranged on the left and right sides of the inner cavity of the box body 1, and the The partition plate 2 divides the inner chamber of the box body 1 into a working chamber 3 and two blowing chambers 4. On the left and right sides of the inner cavity of the body 1, the inner cavity of the working cavity 3 is evenly provided with a number of running plates 5, and a number of heat exchange tubes 7 are evenly embedded in the running plate 5, and the ends of all the heat exchange tubes 7 Part of the blowing chamber 4 is connected through the running plate 5. The inner chamber of the working chamber 3 is divided into several running chambers 6. The inner cavity top wall of the running chamber 6 is fixedly equipped with a temperature sensor 8. The outer side o...

Embodiment 2

[0034] See figure 2 , the difference from Embodiment 1 is: the top of the controller 9 is embedded with a touch screen 91 and a main switch 92, the main switch 92 is located on the right side of the touch screen 91, the controller 9 A microprocessor 93 and a storage module 94 are installed inside, and the microprocessor 93 is respectively connected to the storage module 94, the touch screen 91, the main switch 2, the temperature sensor 8 and the air cooling mechanism 12, and the temperature control is input through the touch screen 91. Standard parameters, and stored in the storage module 94, then use the temperature sensor 8 to detect the temperature in the operating chamber 6, and send the monitoring data to the microprocessor 93, and the microprocessor 93 accepts and calls the temperature control standard in the storage module 94 The parameters are compared. When the temperature detected by the temperature sensor 8 exceeds the temperature control standard parameter, the bu...

Embodiment 3

[0036] See image 3 The difference from Embodiment 2 is that the air-cooling mechanism 12 includes a support frame 121, and the support frame 121 is sleeved on the inner wall of the air-cooled pipe 10. The support frame 121 is a cross-shaped structure, and the support frame 121 The side chamber of the fan 122 is provided with a fan 122, and the fan 122 is fixedly installed on the support frame 121 through a fixed rod 123. The fan 122 is connected to the microprocessor 93, and the air from the outside is drawn by the fan 122 and injected into the air-cooled tube 10, and is cooled by the air. The tube 10 is injected into the heat exchange tube 7, and then the heat in the operation chamber 5 is taken away through the heat exchange tube 7, so that the temperature of the operation chamber 5 can be lowered, thereby ensuring the safe operation of the electrical components in the operation chamber 5.

Abstract

The invention discloses an internal monitoring system and monitoring method for high-voltage electrical equipment. The system comprises a box body; a plurality of supporting legs are uniformly arranged at the bottom end of the box body; partition plates are symmetrically arranged on the left and right sides of an inner cavity of the box body. An inner cavity of the box body is divided into a working cavity and two air blowing cavities by the partition plates; a plurality of operation plates are uniformly arranged in an inner cavity of the working cavity; a plurality of heat exchange pipes areevenly embedded in the operation plate, the ends of all the heat exchange pipes are communicated with an air blowing cavity in a penetrating mode, the operation plate divides an inner cavity of the working cavity into a plurality of operation cavities, temperature sensors are fixedly installed on the top walls of the inner cavities of the operation cavities, and the outer side end of the air blowing cavity is connected with an air cooling pipe in a penetrating mode. According to the invention, the controller can cooperate with the temperature sensor to monitor the temperature change in the operation cavity in real time, and the operation cavity is cooled through the air cooling mechanism, so that the operation safety of the whole device can be protected to the greatest extent, the maintenance frequency of the whole device can be greatly reduced, and the service life of the whole device is prolonged.

Description

technical field [0001] The invention relates to the technical field of electrical equipment monitoring, in particular to an internal monitoring system and monitoring method for high-voltage 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 element in a power plant for the proper operation and delivery of electricity is the electrical equipment. [0003] With the rapid development of the economy, the capacity of my country's power system has expanded rapidly, especially the use of high-voltage electrical equipment such as GIS is increasing. Sulfur hexafluoride (GIS) high-voltage electrical equipment has been widely used in the power sec...
