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

Embodiment Construction
[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0028] Such as Figure 1-Figure 9 As shown, an intelligent power distribution cabinet for power transmission and distribution network includes a cabinet body 1 and a side door mechanism 4 arranged on the side of the cabinet body 1, and two lifting units are arranged on the front and back of the cabinet body 1 3. The front of the cabinet 1 is also provided with a display screen 2, a speaker 7, several status indicator lights 5 and several control buttons 6;
[0029] The side door mechanism 4 includes a driving door mechanism, a driven door mechanism and a connecting rod 14, and the driving door mechanism is transmission-connected with the driven door mechanism...

The invention relates to an intelligent power distribution cabinet for power transmission and distribution networks, which includes a cabinet and a side door mechanism arranged on the side of the cabinet. Two lifting units are provided on the front and back of the cabinet. The cabinet The front of the body is also equipped with a display screen, a speaker, a number of status indicators and a number of control buttons. The intelligent power distribution cabinet for power transmission and distribution network drives the first door panel to move through the driving mechanism, and uses the connecting rod to drive the second door panel to move. , so that the first door panel and the second door panel are located below the first guide rail or the second guide rail. Since the movement process is realized inside the cabinet, it does not occupy external space and is convenient for the operator to work. Not only that, in the frequency control circuit, By adjusting the resistance of the adjustable resistor, the oscillation frequency of the astable oscillator is changed, thereby changing the operating frequency, further improving the practicality of the device.
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...
