Description

Technical Field

[0001] This utility model relates to electrical switchgear. In particular, it relates to a vibration-damping and dustproof remote switchgear. Background Technology

[0002] Electrical switchgear is a device used for controlling and distributing electrical energy. It typically consists of one or more switching devices, protective devices, metering instruments, and connectors, and is connected to power sources and load equipment via cables or wires. Switchgear is mainly used for power distribution and control in power systems, industrial equipment, and buildings. Remote switchgear uses an external computer to transmit signals for control. Existing remote switchgear uses a remote controller installed inside the switchgear to control and monitor electrical switches and transmit data to relevant personnel. However, in long-term unsupervised operating environments, remote switchgear sometimes experiences control failures. Analysis shows that the remote controller contains contactors and other operating devices. These devices generate vibrations during operation, which over time can cause loosening and contact failure, leading to poor contact in the remote controller, a major cause of remote controller failure. Additionally, dust accumulation and high temperatures inside the switchgear during long-term operation also contribute to remote switchgear failure. Utility Model Content

[0019] like Figures 1 to 4 A vibration-damping and dustproof remote switch cabinet includes a switch cabinet housing 10, an electrical switch 11 and a remote controller 12 are provided inside the switch cabinet housing, and the electrical switch 11 and the remote controller 12 are connected by cables.

[0020] The switch cabinet enclosure 10 includes an equipment compartment 1A and a ventilation compartment 1B, which are arranged side by side. The equipment compartment 1A is equipped with an equipment compartment door 17, and the equipment compartment door is equipped with a control panel 17a and a display screen 17b for on-site operation. The ventilation compartment 1B is equipped with a ventilation compartment door 18.

[0021] Electrical switch 11 and remote controller 12 are located in equipment compartment 1A.

[0022] The ventilation chamber 1B includes an exhaust chamber 13 and an intake chamber 14. The exhaust chamber 13 and the intake chamber 14 are arranged vertically, with the intake chamber 14 located on the lower side of the ventilation chamber 1B and the exhaust chamber 13 located on the upper side of the ventilation chamber 1B.

[0023] The remote controller 12 is located on the lower side of the equipment compartment 1A and is mounted on the controller base 20. A connecting rod damper 30 supporting the controller base 20 is provided at the bottom of the equipment compartment 1A, and an elastic limiter 21 supporting the controller base 20 is provided inside the equipment compartment 1A.

[0024] The linkage damper 30 has two linkages 31, which are hinged together at the middle position. The upper end of each linkage has a damping slider 32 connected to the controller base 20, and the lower end of each linkage 31 has a damping slider 32 connected to the equipment compartment 1A. The linkages 31 are hinged to the damping sliders 32, and the two ends of the damping sliders 32 are equipped with spring damping shock absorbers 33.

[0025] The lower end of the controller base 20 is provided with a base slider groove 22, in which the damping slider 32 slides. Two base slider grooves 22 are provided for each connecting rod damper 30, corresponding to the damping sliders 32 at the upper ends of the two connecting rods 31 respectively. The damping sliders 32 are installed in the base slider grooves 22, and the spring damping shock absorbers 33 at both ends of the damping sliders 32 are fixed to the side walls of the base slider grooves 22.

[0026] The bottom surface of the equipment compartment 1A is provided with a box-type slider groove 19, and the damping slider 32 slides within the box-type slider groove 19. Two base slider grooves 22 are provided corresponding to each connecting rod damper 30. The two box-type slider grooves 19 correspond to the damping sliders 32 at the lower ends of the two connecting rods 31, respectively. The damping sliders 32 are installed within the box-type slider grooves 19, and the spring damping shock absorbers 33 at both ends of the damping sliders 32 are fixed to the side walls of the box-type slider grooves 19.

[0027] This invention employs a controller base with elastic support and damping function, which can absorb vibrations generated during remote controller operation, prevent equipment loosening, and ensure contact reliability. The two-link damper, compared to ordinary spring supports, can absorb vibration energy while avoiding resonance, achieving excellent vibration reduction and damping effects.

[0028] In order to improve the ventilation and dust prevention function of the switch cabinet, this utility model adopts an independent air exchange chamber 1B.

[0029] The air intake chamber 14 is provided with an air inlet 15 that connects to the equipment compartment 1A. The air inlet is equipped with an air intake fan 41. The air intake chamber 14 is equipped with a filter screen 42 and a louver 43 that connects to the outside. The exhaust chamber 13 is provided with an exhaust outlet 16 that connects to the equipment compartment 1A. The exhaust outlet 16 is equipped with an exhaust fan 44, and an insect screen 45 is provided between the exhaust chamber 13 and the outside.

[0030] like Figure 4 As shown, under the action of the intake fan 41, outside air enters the intake chamber 14 through the louvers 43, is filtered by the filter screen 42, and enters the equipment compartment 1A through the air inlet 15. The air in the equipment compartment is output to the exhaust chamber 13 from the exhaust port 16 under the action of the exhaust fan 44, and then discharged to the outside through the insect screen 45. The intake fan 41 and the exhaust fan 44 are controlled by the monitoring system in the remote switch cabinet to start and stop.

[0031] The air intake chamber 14 enhances air purification, while the louvers prevent rainwater from entering. Any small amount of rainwater that does get in will settle within the air intake chamber, making it difficult for it to enter the equipment compartment and ensuring the environmental safety of the electrical equipment. Similarly, dust entering the air intake chamber with the air will also settle within it, further improving air purification.

[0032] During periods when exhaust fan 44 is off, a small amount of dust and rainwater may still enter the exhaust chamber. The exhaust chamber allows the rainwater and dust to settle, preventing them from entering the equipment compartment. The insect screen prevents flying insects from entering. Additionally, when the exhaust fan is running, it creates positive pressure within the exhaust chamber, further preventing dust and rainwater from entering.

[0033] The ventilation chamber creates an isolation barrier between equipment compartment 1A and the outside world, preventing dust, flying insects and rainwater from entering, and providing a good purified and cooled environment for the electrical and control equipment in the switch cabinet.

[0034] The remote control device for the switchgear of this invention has a reasonable structure. The remote controller can be stably installed inside the switchgear, preventing equipment from becoming loose and maintaining a reliable connection with the electrical equipment. Air purification and circulation can be achieved inside the switchgear to ensure effective heat dissipation. This invention enables the remote-controlled switchgear to operate stably for a long period, demonstrating good practicality.
