An intelligent monitoring function provided air tank circuit breaker

Abstract

This utility model discloses a gas-insulated switchgear circuit breaker with intelligent monitoring function, including a gas-insulated switchgear circuit breaker housing. Two mounting brackets are symmetrically arranged on one side of the gas-insulated switchgear circuit breaker housing. A cross-shaped mounting plate is installed inside each mounting bracket. A motor is fixedly connected to one side of the cross-shaped mounting plate. The output shaft of the motor passes through the cross-shaped mounting plate and is fixedly connected to a sector gear at one end. A filter screen is installed on the side of the mounting bracket opposite to the gas-insulated switchgear circuit breaker housing. A mounting groove is provided at the bottom of the mounting bracket, and an absorbent sponge is installed inside the mounting groove. This utility model achieves forced air cooling of the switchgear by activating the motor when the gas-insulated switchgear temperature is too high, causing the sector gear to rotate at high speed and creating a negative pressure suction force inside the mounting bracket. This draws outside air into the mounting bracket, and the high-speed airflow into the gas-insulated switchgear causes the temperature inside the air chamber to dissipate to the outside with the airflow.

Technical Field

[0001] This utility model relates to the technical field of gas-insulated switchgear circuit breakers, specifically a gas-insulated switchgear circuit breaker with intelligent monitoring function. Background Technology

[0002] As an important type of power equipment, gas-insulated switchgear is widely used in the field of medium and high voltage switches. In order to ensure that the gas-insulated switchgear can monitor a variety of key parameters in real time during operation, provide early warning of faults, improve the reliability and safety of the equipment, and provide data support for the intelligent management of the power system, monitoring equipment is usually added to the gas-insulated switchgear.

[0003] The monitoring equipment uses temperature and pressure sensors inside each chamber of the gas-insulated switchgear to monitor the temperature and pressure inside the circuit breaker in real time to ensure the normal operation of the circuit breaker. However, if the ambient temperature inside the chamber is too high, it can easily affect the internal insulation performance and gas pressure, thereby affecting the normal use of the gas-insulated switchgear circuit breaker. Utility Model Content

[0004] The purpose of this invention is to provide a gas-insulated switchgear circuit breaker with intelligent monitoring function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas-insulated switchgear circuit breaker with intelligent monitoring function, comprising a gas-insulated switchgear circuit breaker housing, two mounting brackets symmetrically arranged on one side of the gas-insulated switchgear circuit breaker housing, a cross mounting plate arranged inside the mounting bracket, a motor fixedly connected to one side of the cross mounting plate, the output shaft of the motor passing through the cross mounting plate and fixedly connected to a sector gear plate at one end, a filter screen arranged on the side of the mounting bracket away from the gas-insulated switchgear circuit breaker housing, and a mounting groove arranged at the bottom of the mounting bracket, with an absorbent sponge arranged inside the mounting groove.

[0006] As a further preferred embodiment of this technical solution, the mounting bracket is symmetrically provided with rotating seats on both sides of the top, the rotating seats are rotatably connected to the top of the rotating seats, and the top of the rotating blocks are fixedly connected to a waterproof plate.

[0007] As a further preferred embodiment of this technical solution, an adjusting screw is provided between the rotating base and the rotating block. One end of the adjusting screw is fixedly connected to a plum blossom handle, and a nut is threadedly connected to one side of the adjusting screw. The nut is fixedly installed on one side of the rotating base.

[0008] As a further preferred embodiment of this technical solution, a connecting frame is fixedly connected to the side of the gas-insulated switchgear circuit breaker housing facing away from the mounting bracket. Mounting guide rails are symmetrically arranged on both sides inside the connecting frame. A slot is provided on the top of the connecting frame, and the slot corresponds to the mounting guide rail.

[0009] As a further preferred embodiment of this technical solution, a dustproof net is provided inside the mounting guide rail and slot, and a limiting plate is fixedly connected to the top of the dustproof net.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, a gas-insulated switchgear circuit breaker with intelligent monitoring function includes a gas-insulated switchgear circuit breaker housing 1. Two mounting brackets 2 are symmetrically arranged on one side of the gas-insulated switchgear circuit breaker housing 1. A cross mounting plate 3 is arranged inside the mounting bracket 2. A motor 4 is fixedly connected to one side of the cross mounting plate 3. The output shaft of the motor 4 passes through the cross mounting plate 3 and is fixedly connected to a sector tooth disk 5 at one end. A filter screen 6 is arranged on the side of the mounting bracket 2 away from the gas-insulated switchgear circuit breaker housing 1. An installation groove 7 is arranged at the bottom of the mounting bracket 2. An absorbent sponge 8 is arranged inside the installation groove 7.

[0023] When the temperature sensor inside the gas chamber of the gas chamber detects that the ambient temperature is too high, the external control system activates motor 4, whose output shaft drives the sector disk 5 to rotate at high speed, creating a negative pressure suction inside the mounting frame 2. This draws outside air into the mounting frame 2, and the high-speed airflow enters the gas chamber. The temperature inside the gas chamber dissipates to the outside with the airflow, thus achieving forced air cooling of the cabinet. A filter screen 6 is installed on one side of the mounting frame 2 to reduce the entry of debris and dust. The filter screen 6 has a small pore size, and when water comes into contact with it, the filter screen 6 can play a certain role in isolating the water and collecting it in the mounting groove 7. The water is then absorbed by the water-absorbing sponge 8, thus preventing water from entering the gas chamber.

[0024] The mounting bracket 2 has symmetrically arranged rotating seats 9 on both sides of the top. The top of the rotating seat 9 is rotatably connected to a rotating block 10, and the top of the rotating block 10 is fixedly connected to a waterproof plate 11.

[0025] An adjusting screw 12 is provided between the rotating base 9 and the rotating block 10. One end of the adjusting screw 12 is fixedly connected to a plum blossom handle 13. A nut 14 is threadedly connected to one side of the surface of the adjusting screw 12. The nut 14 is fixedly installed on one side of the rotating base 9.

[0026] Rotating the plum blossom handle 13 causes the adjusting screw 12 to rotate inside the nut 14, resulting in the rotating seat 9 and the rotating block 10 being squeezed together, thereby fixing the position of the rotating block 10 and the waterproof plate 11. When the gas-insulated switchgear circuit breaker is working, the waterproof plate 11 can block the water source falling from the top, thereby preventing water leakage or seepage. Furthermore, the waterproof range can be adjusted by adjusting the angle of the waterproof plate 11, thus improving the waterproof effect.

[0027] A connecting frame 15 is fixedly connected to the side of the gas-insulated switchgear circuit breaker housing 1 away from the mounting bracket 2. Mounting guide rails 16 are symmetrically arranged on both sides inside the connecting frame 15. A slot 17 is opened on the top of the connecting frame 15, and the slot 17 corresponds to the mounting guide rail 16.

[0028] The mounting rails 16 and slots 17 are equipped with a dustproof mesh 18 inside. The top of the dustproof mesh 18 is fixedly connected to a limiting plate 19. The limiting plate 19 is located outside the connecting frame 15. A sealing gasket is provided between the limiting plate 19 and the slots 17.

[0029] A dustproof mesh 18 is installed inside the mounting rail 16 and the slot 17 to ensure normal airflow and heat dissipation while reducing the entry of foreign objects and dust. When too much dust accumulates on the dustproof mesh 18, the limiting plate 19 can be pulled upwards to remove the dustproof mesh 18 for cleaning, thus ensuring the overall ventilation effect. A sealing gasket is installed between the dustproof mesh 18, the slot 17, and the mounting rail 16 to ensure the sealing of the connection and prevent the entry of water and dust.

[0030] Multiple adjusting blades 20 are evenly distributed along the height direction inside the connecting frame 15. A rotating gear 21 is sleeved on the rotating shaft surface on one side of the adjusting blade 20, and a toothed belt 22 meshes with the surface of the rotating gear 21.

[0031] A protective housing 23 is fixedly connected to the side of the connecting frame 15 near the rotating gear 21. A motor 24 is fixedly connected to the side of the protective housing 23 away from the connecting frame 15. The motor 24 and the rotating shaft of the adjusting blade 20 are fixedly connected.

[0032] The start motor 24 drives the adjusting blades 20 and the rotating gears 21 to rotate, and transmits power to other rotating gears 21 through the toothed belt 22, causing multiple adjusting blades 20 to rotate accordingly. This adjusts the gap between two adjacent adjusting blades 20 to control the air volume of the gas chamber and adapt to the needs of different working conditions. The adjusting blades 20 adopt an arc-shaped structure so that when water comes into contact with the adjusting blades 20, it can move downward through the arc surface to avoid entering the interior of the gas chamber.

[0033] This utility model provides a gas-insulated switchgear circuit breaker with intelligent monitoring function, and its specific working principle is as follows:

[0034] During use, a temperature sensor is installed inside the gas chamber of the gas cabinet to monitor the ambient temperature of the chamber in real time. When the temperature of the chamber rises abnormally, the circuit breaker can be briefly disconnected to cut off the current and reduce heat generation. At the same time, the external control system enables motor 4 to work, and its output shaft drives the sector disk 5 to rotate at high speed, creating a negative pressure suction inside the mounting frame 2, thereby drawing outside air into the mounting frame 2. The high-speed airflow enters the gas cabinet, and the temperature inside the chamber enters the connecting frame 15 with the airflow, allowing the high-temperature air to dissipate into the outside air, thus achieving forced air cooling of the cabinet. As needed, motor 24 can be activated, and its output shaft drives the adjusting blades 20 and rotating gears 21 to rotate. The power is transmitted to other rotating gears 21 through the toothed belt 22, causing multiple adjusting blades 20 to rotate accordingly. This adjusts the gap between two adjacent adjusting blades 20 to control the airflow of the gas cabinet and adapt to the heat dissipation requirements under different working conditions.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
