A new type of power distribution cabinet for power transmission network

Abstract

The invention relates to a novel power distribution cabinet used for a power transmission network. The novel power distribution cabinet comprises a cabinet body, wherein the cabinet body is provided with a cabinet door; the cabinet door is provided with an indicating mechanism, a display screen, a handle, a loudspeaker and a control panel from top to bottom in sequence. According to the novel power distribution cabinet used for the power transmission network, a vertical reflector plate and a transverse reflector plate are rotated through a drive motor, so that light direction propagation of an indicator lamp is controlled, light rays are diffracted by using through holes, and the irradiation space of the light rays is enlarged; therefore, the display effect of the indicating mechanism is strengthened to draw the attention of workers to carry out corresponding operation in time; moreover, in a power supply circuit, the model of an integrated circuit is RT9173, the interior is provided with a highly operational amplifier, the change of a load can be quickly responded, and the novel power distribution cabinet is free of a dead zone; and furthermore, the novel power distribution cabinet also has the functions of short circuit protection, overheating protection and the like, the reliability of the power supply circuit is further improved, and the reliability of the power distribution cabinet is improved.

Description

technical field [0001] The invention relates to a new type of power distribution cabinet for power transmission network. 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] However, when the existing power distribution cabinets are used to indicate the workin...

Problems solved by technology

[0003] However, when the existing power distribution cabinets are used to indicate the working status, the indicator light structure is single, and the relative display content is relatively simple, which is not enough to attract the attention of the staff. Flashing strengthens the reminder, but the indicator light circuit is complex and has low reliability. Not only that, the internal power supply of the power distribution cabinet responds slowly to the load, resulting in unstable power supply, and the lack of corresponding protection functions further reduces the reliability of the power distribution cabinet. sex
