Switch cabinet with stable fireproof performance

Abstract

The invention discloses a switch cabinet with a stable fireproof performance. The switch cabinet comprises a switch cabinet body, a buzzer and a warning lamp. The switch cabinet body is internally provided with a support track. According to the switch cabinet with the stable fireproof performance, by additionally arranging aerosol with a stable performance and a clean gas on two sides in the switch cabinet body, the detection temperature of the aerosol is 170 + / -10 DEG C, thereby achieving the effective fire-prevention function to the internal portion of the switch cabinet body, simultaneouslywrapping the secondary cable bridge at the internal portion of the switch cabinet body by a fire-proof material and playing the role of fire prevention, and through the adjustable air exhaust detection device, the adjustable air exhaust detection device can perform detection in different easy-heating contact ranges, thereby achieving the timely detection of the air temperature in the range, achieving the air current in the range and having the effectual fire-prevention effect at the internal portion of switch cabinet body.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a switch cabinet with stable fireproof performance. Background technique [0002] The main function of the switchgear is to open and close, control and protect the electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switchgear mainly include circuit breakers, insulating parts, operating mechanisms, With the development of power grid technology, especially the development of distribution network technology, the switchgear is required to develop in the direction of miniaturization and intelligence. [0003] When the existing switchgear is in use, due to the poor sealing performance of the switchgear itself, it is easy to cause the fire of the switchgear and the continuous operation of the switchgear, and because each switchgear contains more terminals or contacts, when indivi...

Problems solved by technology

[0003] When the existing switchgear is in use, due to the poor sealing performance of the switchgear itself, it is easy to cause the fire of the switchgear and the continuous operation of the switchgear, and because each switchgear contains more terminals or contacts, when individual contacts The head is hot and not detected in time, which often leads to a fire in the switchgear. The existing detection method for contacts and terminals is: fixed detection, that is, a single temperature detection sensor is fixed on the outside of the contact. However, other detection methods such as terminals When the temperature sensor is not installed in the overheating situation, it cannot be detected, and there are certain safety hazards. Therefore, we propose a switchgear with stable fireproof performance
