Description

Short-circuit protection device is prevented to electric test bench

Technical Field

The utility model relates to the field of test auxiliary tools, in particular to an anti-short circuit protection device of an electric test stand.

Background

In the occasions such as overhaul sites and training classrooms, electric tests such as component wiring and power module live test are often carried out, so that the purposes of verifying the functions of an electric loop, verifying the usability of components, improving labor skills and the like are achieved. However, due to subjective and objective factors such as uneven technical levels of personnel and unknown availability of components, abnormal events such as wiring errors, power module damage and the like often occur, and the power supply is short-circuited. Although the small-capacity power supply can be configured to be switched off in time when the power supply is switched off, the purposes of preventing accidents from expanding and reducing losses are achieved, the experimental equipment is inevitably damaged due to the release of instantaneous short-circuit current energy due to the problem of the time of the tripping operation of the air-conditioner, and the difficulty is improved for later maintenance and experiments. In order to avoid the loss caused by short circuit in the electrical test, the short circuit prevention device of the electrical test stand is manufactured.

Drawings

Fig. 1 is an electrical schematic of the present utility model.

Fig. 2 is a schematic structural view of the present utility model.

The device comprises a 1-power input/output part, a 101-power input, a 102-power output, a 2-switch, a 3-energy absorbing part, a 4-box body, a 5-energy absorbing element socket and a 6-test socket.

Detailed Description

For a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings.

As shown in figure 2, the energy absorbing element socket 5 of the box body can be selectively provided with a 60-100W incandescent lamp according to an actual test object, the device can be put into use, the test object receives power from the test socket 6 on the box body, and the power is supplied after the switch on the box body is turned on. The load is very small or the wiring is not wrong, the incandescent lamp cannot be lightened (or reddish), if the load is short-circuited due to the reasons of wrong wiring, failure of components and the like in the test, the incandescent lamp absorbs short-circuit energy, and the short-circuit degree is different from the brightness of the incandescent lamp.

One end of the indicator socket 5 is connected with the live wire L of the power plug 1 through the switch 2, and the other end of the indicator socket 5 is connected with the live wire L terminal of the test socket 6, namely, the live wire forms a series circuit through the switch 2 and the indicator socket 5.

When the device is adopted for experiments, equipment damage caused by line short circuit can be avoided, the fault range is reduced, the difficulty is reduced for later-stage repair, the power load level of experimental equipment can be reflected, and the safety of personnel and equipment can be ensured to a certain extent.

The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
