Description

Safe power consumption switch board

Technical Field

The utility model relates to an electricity control cabinet especially relates to a safe electricity control cabinet of using when production line overhauls.

Background

The maintenance power box is a safety electricity taking device for power consumers, the device utilizes the circuit breaker to control the on-off of the power supply in the main circuit and each branch, and a socket or a plug is utilized to provide a power source for the power consumers. The safety and the reliability of electrical equipment such as electrician tools used on site are ensured, and the personal safety of the electric personnel is ensured. The current maintenance power box generally only provides a plug or a socket of 380V/220V for illumination, electric tools and the like.

But when the dark and wet working area is overhauled, the illumination below the safe working voltage (24V) is required. The electric workers are required to perform complicated wiring during each overhauling and cleaning, and the electric workers are inconvenient and unsafe.

fig. 2 is a schematic diagram of the present invention.

Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings.

As shown in fig. 1, the utility model comprises a cabinet body, a cabinet door, a switch module 1, a socket module 2 consisting of four sockets and three sockets; the cabinet body passes through pivot swing joint with the cabinet door, and the power source is installed to the back of the cabinet body, and cabinet body internally mounted has 300KVA safety transformer's power conversion module 3, and the transparent glass through the front panel of the cabinet body is visual. The switch module 1 comprises a main residual current circuit breaker switch QF0 and 6-socket residual current circuit breaker switches QF1-QF6, wherein the rated currents of the residual current circuit breakers are 63A and 16A respectively. One end of the QF1-QF5 circuit residual-current circuit breaker switch is connected with a power interface through a main residual-current circuit breaker switch QF0, and the other end of the QF1-QF5 circuit residual-current circuit breaker switch is directly connected with XS1-XS5 of the socket module respectively. One end of the QF6 circuit leakage breaker switch is connected with a power interface through a main leakage breaker switch QF0, and the other end of the QF6 circuit leakage breaker switch is connected with XS6-1 and XS6-2 of the socket module through a transformer. The socket and the switch module are installed on the front panel of the cabinet body. A safety lock is also arranged between the cabinet body and the cabinet door.

As can be seen from fig. 2, the working principle of the present invention is as follows:

on one hand, the safety electricity utilization control cabinet is connected with 380V/220V mains supply through a power interface, and then the mains supply is connected with XS1-XS5 of a socket module on a front panel of the cabinet body through an electric leakage circuit breaker, so that 380V/220V electricity is provided for workers during maintenance.

On the other hand, after the safety control cabinet is connected with mains supply through the power interface and passes through the residual current circuit breaker, the mains supply is input into the power conversion module, the mains supply is reduced into 12V-24V safe voltages with different levels through the transformer of the power conversion module, and the 12V safe voltages are used for illumination through XS6-1 and XS6-2 of the socket module.

The main leakage circuit breaker controls the on and off of the main circuit, and the leakage circuit breaker of each branch circuit controls the on and off of each branch circuit, so that the use is convenient.
