Description

Technical Field

[0001] The invention relates to the technical field of fault finding, in particular to a portable wireless insulation fault finding device suitable for an AC power supply system for a transformer substation. Background Art

[0002] Substation refers to the place in the power system where voltage and current are transformed, electric energy is received and distributed. The substation in the power plant is a step-up substation, and its function is to step up the electric energy generated by the generator and feed it into the high-voltage power grid. The communication AC power supply system is generally composed of the following: the main AC power supply is generally the city power, and wind power can be used in special cases, and the backup AC power supply is oil generator sets or gas generator sets. AC power supply is a modern word, a proper noun, which refers to the plug and socket used to connect the AC power provided by the city power, so that household appliances and portable small devices can be powered and used. The AC power supply system can be used to transmit and use the current of the substation. In order to prevent the AC power supply from failing, it can be regularly fault-finding and detecting the AC power supply; When the portable wireless insulation fault detection device for the AC power supply system of the substation is in use, due to the different installation heights of the substation, the staff is usually required to hold up the detection end of the fault detection device with their hands, which causes the staff to easily cause arm fatigue due to long-term hand-raising, affecting the efficiency of finding and detecting the AC power supply fault of the substation. At the same time, when the portable wireless insulation fault detection device for the AC power supply system of the substation is in use, in order to facilitate the use of the instrument, the device is usually set to be relatively small and easy to carry, but the instrument is small and easy to slip from the palm of the staff and cause damage. Summary of the invention

[0003] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a portable wireless insulation fault detection device suitable for an AC power supply system for a substation. When the device is detecting the power-on condition of the AC power supply of the substation, the fastening nut is screwed to connect the first connecting rod and the second connecting rod. The sliding of the adjusting top rod and the adjusting hollow tube allows the adjusting top rod to be pulled out from the inside of the adjusting hollow tube to adjust the length of the adjusting hollow tube. The height of the electric pen can be adjusted by extending the adjusting top rod. When the electric pen is powered on for detecting the power-on condition of the AC power supply of the substation, the height of the electric pen can be adjusted. After the height of the electric pen is adjusted, the insertion rod is pushed to one side to penetrate the adjusting hollow tube and extend into the inside of the adjusting top rod to fix the length of the adjusting top rod. The movable bead and the movable seat are used to make the orientation of the electric pen adjustable. When the device is detecting the power-on condition of the AC power supply of the substation, the insertion rod is pushed to one side to penetrate the adjusting hollow tube and extend into the inside of the adjusting top rod to fix the length of the adjusting top rod. The movable connection between the movable bead and the movable seat allows the orientation of the electric pen to be adjusted. When the fault is found and detected, the staff cannot raise their hands for detection, which relieves the fatigue of the staff's arms. When the staff holds the hand for detection, the staff's palm can enter the inside of the palm splint, and the movement of the slide plate and the palm splint can make the palm splint arch backward according to the curvature of the staff's palm, and the slide plate can pull the second spring, so that a pulling force can be formed between the slide plate and the fault detector, and the palm splint and the slide plate can clamp the staff's palm together, and the staff's multiple fingers can enter the inside of the open box, so that the rubber block can be squeezed by the staff's fingers and drive the movable plate to squeeze the first spring.
