technical field

The utility model relates to the technical field of a mobile power supply for electrical testing, in particular to a mobile power supply device for electrical testing that is convenient for quickly finding power failures.

Background technique

With the continuous development of science and technology, there are higher requirements for the power supply reliability of the power grid. In order to prevent accidents when electrical equipment is put into operation or during operation, and to discover potential defects in the equipment in time, electrical equipment must be tested. Since most of the test instruments need to be powered on to complete the test, the test instruments need to be connected to an AC 220V power supply to work. In actual work, the test mobile power board only consists of binding posts, double-throw switch, and socket. When in use, the low-voltage power supply needs to be drawn from the low-voltage power distribution cabinet of the substation to connect to the mobile power board. However, in practical applications, it often occurs that the power supply cannot supply power, and it is impossible to visually determine the fault. Once such a situation is encountered , It often takes a lot of time to find the mobile power board step by step from the AC access point, which is very troublesome and greatly reduces the operating efficiency. Checking whether the mobile power board is working normally is the premise guarantee to ensure that the test work can be carried out smoothly. Therefore, there is an urgent need for a mobile power board that can conveniently and intuitively determine the location of the fault, so as to conveniently and intuitively check the power supply of the mobile power supply. .

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art and provide a mobile power supply device for electrical testing with simple structure and convenient operation. When the device fails, it can quickly and intuitively judge the fault location, thereby effectively saving Time to troubleshoot issues.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a mobile power supply device for electrical testing, including an insulating box, one side of the insulating box is provided with a terminal, the other side of the box is A test plug-in board is set, a double-throw knife switch and two indicator lights are set on the cover plate of the box body, and the two ends of the double-throw knife switch are respectively connected to the terminal and the test plug-in board through wires inside the box body , the two indicator lights are respectively connected in series with a resistor and connected to both sides of the double-throw switch.

The inside of the box body is provided with a wire clamping groove.

A circuit board is arranged in the box body, and the connecting terminals, the test plug board, the double-throw knife switch, the indicator light and the resistor are all arranged on the circuit board, and connected to the box body respectively. The through hole corresponding thereto exposes the box body.

The indicator lights are light emitting diodes.

The utility model adopts the insulating box body to seal the connection circuit of each component in the insulating box body, effectively guarantees the safety and reliability of the operation of the mobile power supply, and is more convenient for the connection of the terminal and the plugging operation of the socket. At the same time, through The wire clamping groove arranges and fixes the wires, avoiding the occurrence of intercrossing and short-circuiting among the internal wires; more importantly, an indicator light is connected in parallel on both sides of the double-throw switch, thus effectively realizing when the movement fails, Quickly and intuitively determine the function of the fault. After the AC power is connected, the indicator light at the front of the double-throw switch is on, indicating that the AC power side of the mobile power supply device is normal. If it is not on, it means that the AC power supply is out of power or the AC power cord is disconnected, and the fault is at the front of the mobile power supply unit.

When the indicator light at the front of the double-throw switch is on, close the double-throw switch, and the indicator light at the back is on, indicating that the electrical test mobile power supply device is normal and the electrical test can be performed. If it is not on, it means that the mobile power supply device has a double-throw knife switch fuse blown, poor contact in the device, poor contact of the internal wires, etc., and the insulating box can be opened in a targeted manner to overhaul the internal circuit. The utility model is simple, fast, safe and reliable.
