Embodiment Construction

[0022] Such as figure 1Shown is a structural diagram of an automated power frequency withstand voltage test device in insulator oil. The beam 1 is fixed on the workbench 5 through the left beam frame 2 and the right beam frame 10. On the workbench 5, the area to be tested, the ultrasonic cleaning device 15, the air drying device 16, the insulating container 6 and the tested area are arranged in sequence, and the main body of the lifting machine is 9. The rolling pair is formed by the lateral moving wheel 8 and the beam 1. The lateral moving wheel 8 is driven by the lateral moving motor, thereby driving the hoist to move laterally along the beam. The lifting arm 11 is fixed on the main body 9 of the hoisting machine. Driven by a motor, a suspension hook 12 is connected to the end of the lifting arm 11, and both the lateral movement motor and the lifting motor are servo motors and are connected to the control device. The first insulator to be tested 13 and the second insulator ...

Description

technical field [0001] The invention relates to the field of insulator test equipment, in particular to an automatic power frequency withstand voltage test equipment in insulator oil. Background technique [0002] Insulators are an important part of building a power grid and ensuring the safe operation of the power grid. The working environment of insulators is harsh and has high requirements for reliability. Therefore, insulators need to be tested for reliability before use, such as power frequency spark voltage test and power frequency resistance Voltage test, and power frequency withstand voltage test is the most direct, effective and authoritative method to judge the dielectric strength of insulators. However, the currently known insulator power frequency withstand voltage test equipment has a low degree of automation, and many people are required to lift and carry out complex assembly during the test. At the same time, there are many types of insulators and difficult to...
