Description

Technical Field

[0001] The utility model relates to the technical field of transformer substation maintenance equipment, in particular to a transformer substation fire extinguishing device. Background Art

[0002] Smart substations are intelligent devices that use advanced, reliable, integrated and environmentally friendly equipment. They take the digitalization of the entire station information, the networking of the communication platform, and the standardization of information sharing as the basic requirements. They automatically complete basic functions such as information collection, measurement, control, protection, metering and detection. At the same time, they have advanced functions such as supporting real-time automatic control of the power grid, intelligent regulation, online analysis and decision-making, and collaborative interaction. Smart substations mainly include intelligent high-voltage equipment and unified information platform for substations. Intelligent high-voltage equipment mainly includes intelligent transformers, intelligent high-voltage switchgear, electronic transformers, etc. The unified information platform for substations has two functions: one is the horizontal information sharing of the system, which is mainly manifested in the unification of information acquisition by various upper-level applications in the management system; the other is the standardization of the vertical information of the system, which is mainly manifested in the transparency of each layer's support for its upper-level application. At present, people's production and life have higher and higher requirements for power supply reliability and safety. Most smart substations are located in harsh outdoor environments and have achieved unmanned operation. Since the electrical equipment inside the electrical cabinet is in operation for a long time, it will generate heat when powered on. Especially in hot weather seasons, when the temperature is too high, it is very easy to cause fire accidents.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN220025937U discloses a substation fire extinguishing device, including a protection box, the upper and lower sides of the outer wall of the protection box are fixedly connected with mounting blocks, and the inner wall of the protection box is fixedly connected with a first fixing plate and a second fixing plate. The utility model is installed on the side wall of the substation by means of mounting blocks, bolts and nuts. By arranging a smoke sensor and a carbon dioxide fire extinguisher, the smoke concentration of the air inside the substation is continuously detected by the smoke sensor. When a fire occurs, a signal can be sent to the main controller in time, and the valve controller is controlled by the main controller to open the electronic valve, so that the carbon dioxide fire extinguisher can extinguish the fire in the substation. This solves the problem that the existing substation maintenance equipment can only dissipate heat for the substation. Despite continuous heat dissipation, when there is still a possibility of fire, when a fire occurs, the staff often cannot discover and extinguish the fire in time, which can easily lead to a chain disaster.

[0005] However, the above patent still has problems that need to be improved during actual use. The most obvious one is the method of using bolts to install the entire fire extinguishing device on the side wall of the substation, which is cumbersome and laborious to operate and reduces the installation efficiency.

[0006] To this end, we proposed a substation fire extinguishing device to solve the above-mentioned drawbacks. Utility Model Content
