An intelligent power distribution cabinet for power transmission system

Abstract

The invention discloses an intelligent-type power distribution cabinet for a power transmission system, and the cabinet comprises a cabinet body. The cabinet body is provided with a cabinet door, and the cabinet door is sequentially provided with a switch, a work indication lamp, a sound generation device, a handle, a display screen and a state indication mechanism from the top to the bottom. The cabinet enables a semispherical reflection plate to move towards the state indication lamp through the rotation of a drive motor in a strong light unit, thereby changing the propagation direction of light emitted by the state indication lamp towards the cabinet door, enabling the light intensity of the state indication lamp to be higher, and attracting more attention of a worker so as to carry out corresponding operation. Moreover, an integrated circuit in an audio output circuit is low in power consumption, is large in power voltage range, and is low in distortion, thereby improving the practicality and reliability of the audio output circuit. Meanwhile, the cabinet is small in number of external elements, reduces the production cost, and improves the market competiveness.

Description

technical field [0001] The invention relates to an intelligent distribution cabinet for a power transmission system. 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] During the operation of the existing power distribution cabinet, in order to facilitate th...

Problems solved by technology

[0003] During the operation of the existing power distribution cabinet, in order to facilitate the personnel to intuitively observe the working conditions of various states, there are usually several status indicator lights, but the status indicator lights generally have a single structure and relatively simple display content, which is not enough to cause work. The attention of personnel, even if some power distribution cabinets are designed to enhance the display effect of the indicator lights, these circuits are complicated in technology, high in energy consumption and low in reliability. Not only that, the speakers on the power distribution cabinet usually have poor voice circuit performance, It often leads to voice distortion, which reduces the reliability of the device, and the single function of the device makes it unable to meet the high intelligence requirements of the staff
