Problems solved by technology

However, after the side door of the existing power distribution cabinet is opened outward, a part of the occupied area is often increased. In a narrow closed work site or when the power distribution cabinets are closely arranged on site, the side door usually cannot be opened smoothly, resulting in the staff unable to enter the distribution cabinet. Not only that, the internal circuit of the power distribution cabinet has a single operating frequency and cannot output multiple frequency signals, which reduces the practicability of the power distribution cabinet

Abstract

The invention relates to an intelligent power distribution system for power transmission and distribution networks. The cabinet comprises a cabinet body and a side door mechanism arranged on one side face of the cabinet body. Two hoisting units are arranged on the front and back of the cabinet body. A display screen, a loudspeaker, a plurality of indicator lamps and a plurality of control keys are arranged on the front of the cabinet body. According to the intelligent power distribution system for power transmission and distribution networks, a first door plate is driven to move through a drive mechanism. A second door plate is driven to move by employing a connection rod. Therefore, the first door plate and the second door plate are located below a first guide rail or a second guide rail. The moving process is realized in the cabinet body, therefore, external space is not occupied, and an operator can work conveniently. Moreover, in a frequency control circuit, the oscillation frequency of an astable oscillator is changed by regulating the resistance value of an adjustable resistor, therefore, the working frequency is changed; and the practicability of the equipment is further improved.

Description

technical field [0001] The invention relates to an intelligent power distribution cabinet for power transmission and distribution networks. Background technique [0002] Power distribution cabinet is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch, and the circuit can be cut off or alarmed by means of a protective device in case of failure or abnormal operation. The power distribution cabinet can also display various parameters in operation with the help of measuring instruments, and can also adjust some electrical parameters, and prompt or send out signals for deviations from normal working conditions through indicator lights and speakers. [0003] In order to more intuitively observe the operation status of the in...
