Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as Figure 1-4 As shown, a kind of electrical switchgear that can automatically extinguish the fire includes a cabinet body 12, a container bottle 1 and a plurality of automatic nozzles 3 are arranged in the cabinet body 12, a non-conductive fire extinguishing agent is housed in the volume bottle 1, specifically heptafluoropropane, and the volume bottle 1. The fire extinguishing agent release pipe 2 is connected to multiple automatic nozzles 3. The fire extinguishing agent release pipe 2 is spirally fixed inside the cabinet body 12. The automatic nozzle 3 includes a valve body 5 with a release pipe connection 8 at one end, and the release pipe connection 8 is an internal thread provided on the valve body 5 for connecting with the fire extinguishing agent release pipe 2. A first cavity 13 is provided inside the end of the valve body ...

Abstract

The invention discloses an electrical switch cabinet capable of automatically extinguishing fire. The electrical switch cabinet comprises a container bottle, a plurality of automatic nozzles and a fire extinguishing agent release tube, wherein the automatic nozzles comprise valve bodies, first cavities, second cavities, connecting channels, temperature sensing driving components, ejector pins, sealing balls and eccentric supporting springs; the temperature sensing driving components are capable of sensing the temperature of high-temperature gas in the electrical switch cabinet, taking action,driving the sealing balls to move, and opening the connecting channels, so that a non-conducting fire extinguishing agent in the container bottle can be sprayed out so as to extinguish fire; since thefire extinguishing agent is non-conducting, no secondary harm can be caused during the fire extinguishing process; through the arrangement of more than one automatic nozzle in the electrical switch cabinet, the automatic extinguishing of a fire disaster point can be accurately achieved and then the perfect conditions of the other components in the electrical switch cabinet can be guaranteed to the greatest extent; and furthermore, the temperature sensing driving component is sensitive to act, capable of controlling the opening and closing of the automatic nozzles, reliable in running, so thatthe running safety of the electrical switch cabinet can be effectively improved, no extra power source is needed during the use, and the reuse can be achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to an electric switch cabinet capable of automatic fire extinguishing. Background technique [0002] Switchgear is a kind of electrical equipment that provides installation and fixation for various electrical appliances. Its main function is to open and close, control and protect electrical equipment during power generation, transmission, distribution and power conversion in the power system. After the switchgear has been in operation for a long time, the internal electronic components will increase due to aging, oxidation or operating vibration, resulting in an increase in the contact resistance of the diversion position and a large amount of heat. If the heat cannot be dissipated through the cooling holes of the switchgear, the Accumulation will intensify the oxidation of the contact position, forming a vicious circle, and disasters such as arcing or burning wil...
