Alternating-current low-voltage power distributing cabinet capable of being controlled remotely

Abstract

The invention discloses an alternating-current low-voltage power distributing cabinet capable of being controlled remotely. The bottom of a cabinet body is provided with cushion blocks. The lower portion of the cabinet body is provided with cooling groove holes. The cabinet body is provided with a cabinet door. An instrument board is embedded into the upper portion of the cabinet body and provided with a display screen, instruments, a conversion switch and working indicating lamps. The top of the cabinet body is provided with a cooling fan, a sound-light alarm device and an anti-theft device. The cooling fan is provided with a dustproof ventilation screen. A bus bar, a combined bus-bar clamp, a breaker, a current transformer, an insulator, a knife switch, a temperature sensor and a humidity sensor are arranged in the cabinet body. The display screen, the sound-light alarm device, a wireless communication device, the temperature sensor and the humidity sensor are electrically connected with a control module. The alternating-current low-voltage power distributing cabinet capable of being controlled remotely is reasonable in structural design and wide in application range, and the power distributing cabinet damage prevention capacity and anti-theft capacity are improved effectively while stable operation of the power distributing cabinet is guaranteed.

Description

technical field [0001] The invention relates to the technical field of AC low-voltage power distribution cabinets, in particular to an AC low-voltage power distribution cabinet that can be remotely monitored. Background technique [0002] The AC low-voltage power distribution cabinet is suitable for power distribution systems with AC 50Hz, rated working voltage 380V, and rated working current up to 3150A for power users such as substations, power plants, factories, mines, and enterprises. Indoor installations for distribution and control purposes. The existing AC low-voltage power distribution cabinet has the characteristics of high breaking capacity, good dynamic stability, flexible electrical scheme, convenient combination, seriality, strong practicability, novel structure and high protection level, and can be used as an update product for low-voltage complete switchgear use. [0003] In the power system, the reliability and safety of power supply are very important. How...

Problems solved by technology

However, in some areas where earthquakes often occur, the service life of AC low-voltage power distribution cabinets is greatly affected.

In addition, the existing inspection methods for AC low-voltage power distribution cabinets can only be manually inspected on-site to check the working status of AC low-voltage power distribution cabinets, and real-time monitoring cannot be carried out. When the AC low-voltage power distribution cabinet fails, supervisors or management personnel It is impossible to know and deal with it in real time, and it is also impossible to quickly and accurately locate and troubleshoot in a timely manner, which brings great inconvenience to the management personnel

At the same time, the power distribution cabinet is installed in the wild or in a place with poor public security, which cannot be well monitored and inspected. Often, the power distribution cabinet is stolen or damaged, which brings certain economic losses to the relevant units or enterprises.
