[0001] This utility model relates to the field of power equipment maintenance technology, and in particular to a power equipment fault detection and troubleshooting device. Background Technology

[0002] Electrical equipment is a power production and consumption system composed of power generation, transmission, transformation, distribution, and consumption. It converts primary energy from nature into electricity through power generation devices, and then supplies this electricity to various users through transmission, transformation, and distribution. Transformers are a type of electrical equipment, while online monitoring instruments are devices that continuously or periodically monitor the condition of the equipment under test while it is in operation. If a transformer malfunctions, the monitoring instrument will transmit fault information to personnel through warning lights and displays, facilitating maintenance and inspection.

[0003] In practice, the multimeter requires electricians to be extremely careful when operating it because of its tiny probe. Even a slight tremor of the hand can easily cause the probe to separate from the wire, increasing the difficulty of the work and reducing the efficiency of troubleshooting. At the same time, its cable is easy to get tangled on the meter body, which is not only inconvenient to carry, but also difficult to untangle quickly when used again, further affecting the efficiency of troubleshooting. Utility Model Content

[0004] One objective of this invention is to provide a fault detection and troubleshooting device for power equipment. This invention addresses the problems mentioned in the background above, where, in actual operation, the multimeter requires electricians to be extremely careful due to the small size of its testing probe. Even slight hand movements can easily cause the testing probe to separate from the wire, increasing the difficulty of the work and reducing the efficiency of troubleshooting. At the same time, its cable is easily tangled on the meter body, which is not only inconvenient to carry but also difficult to untangle quickly for the next use, further affecting the efficiency of fault diagnosis.

[0007] The testing pen consists of a handle and a testing needle. The end of the testing needle has a wire clamping port, and a wire clamping assembly for clamping the testing needle with the power equipment wire is installed inside the testing needle near the wire outlet.

[0008] The winding assembly includes a positioning shaft installed inside the multimeter, and a winding roller is connected to the outside of the positioning shaft by a spiral spring.

[0009] The wire clamping assembly includes two slide rods symmetrically arranged. A pressure plate is threaded onto the top of each slide rod. Limiting posts are fixedly installed on the outer side of each slide rod. A positioning frame is provided between the two limiting posts. A column is fixedly installed inside the positioning frame. A return spring is provided at one end of the column, and an adjustment assembly for downwardly moving the slide rod and the pressure plate is installed at the other end of the column.

[0010] Preferably, the handle is made of rubber.

[0011] Preferably, the multimeter has an outlet for cable retraction.

A cam is fixedly provided at one end of the rotating shaft corresponding to the column on its outer side, and a rotating handle is fixedly provided at both ends of the rotating shaft.

[0017] The beneficial effects of this utility model are:

[0018] This invention effectively prevents the detection needle from separating from the wire due to shaking, thus avoiding increased work difficulty and reduced troubleshooting efficiency. During use, the operator places the testing pen close to the power equipment's wire, positions the wire at the wire-clamping opening of the detection needle, and then rotates the handle. This causes the cam connected to the outer side of the rotating shaft to press the column inwards towards the detection needle. At this time, the sliding rod, in cooperation with the positioning frame and the limiting column, moves the pressure plate inwards at the wire-clamping opening of the detection needle, locking the wire to the detection needle. This prevents the detection needle from separating from the wire due to shaking during power equipment fault diagnosis. After the test is completed, the handle is reversed, and the pressure plate resets under the action of the return spring, allowing the wire to be pulled out. Therefore, this structure improves the stability during testing and greatly enhances the efficiency of power equipment fault detection and troubleshooting.

[0019] The utility model discloses a winding subassembly is provided with, after the detection of electric power equipment is completed, and the detection pen is connected with the multimeter through winding subassembly, and when using, only needs to pull out the detection pen outward and can carry out the troubleshooting of electric power equipment, when not using, the detection pen will be under the reset action of vortex spring and be wound in the winding roller in the multimeter inside, and the detection pen can be clamped in the both sides of multimeter through the positioning seat, so as to facilitate next time use, and further, the simple structure, convenient operation can effectively solve the problem that cable is wound on the table body, and not only inconvenient to carry, but also difficult to quickly unfold next time.
