Background technique

Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. Commonly used in various power generation, distribution and substations. The purpose of the distribution box: to distribute electric energy reasonably, and to facilitate the opening and closing operation of the circuit. It has a high level of safety protection and can intuitively display the conduction state of the circuit. It is easy to manage, and it is helpful for maintenance when a circuit failure occurs. Structural characteristics and use classification: (1) Fixed panel switch cabinet, often called switch board or power distribution panel. It is a kind of open switchgear covered by a panel. The front has a protective effect, and the back and sides can still touch the live parts. The protection level is low, and it can only be used in industrial and mining enterprises with low requirements for power supply continuity and reliability. Centralized power supply for transformer room. (2) Protective (that is, closed) switchgear refers to a low-voltage switchgear that is closed on all sides except the installation surface.

Bases are arranged on the bottom of the box, and hinges are arranged on the left side of the box. The protective door is installed on the hinge On the left side, and the inside of the protective door is provided with a circuit indication diagram, the outside of the protective door is provided with an alarm flashing light, and a working indicator light is provided below the alarm flashing light, and a nameplate is provided below the working indicator light. The alarm flashing light is electrically connected with the insulation sensor.

Preferably, the protective door and the box are connected by hinges.

Preferably, there are four screws in total, and the four screws are respectively installed at four corners of the electric board.

Preferably, the insulated sensor and the insulated circuit are connected by connecting wires.

Preferably, there are three distributors in total, and the three distributors are respectively installed below the main distributor.

Compared with the prior art, the utility model has the beneficial effects as follows: a power distribution box with automatic power failure alarm has a scientific and reasonable structure, safe and convenient operation, and is equipped with an insulation sensor that can sense the line insulation layer inside the power distribution box If the insulation layer is damaged by aging, the sensor will control the alarm flash to issue an alarm, reminding the staff to carry out maintenance in time, effectively avoiding the impact of the user's electricity consumption and the occurrence of circuit safety accidents caused by the short circuit of the later line due to the aging of the insulation layer and other damage. property loss.
