Intelligent AC withstand-voltage test system and full-automatic high-voltage test box special for same

Abstract

The invention discloses an intelligent AC withstand-voltage test system which comprises an AC withstand-voltage tester, a high-voltage test box and a control part. The intelligent AC withstand-voltage test system is characterized in that the high-voltage test box comprises a box body frame, a hopper, an insulation test box, a circulating box, a chain wheel, a chain wheel support rod, a first cylinder, a second cylinder, a fourth cylinder, a fifth cylinder and a sixth cylinder; and the control part comprises a power supply, a logic circuit, an overcurrent detection circuit and a timing circuitand used for controlling the work of all cylinders. When the test system is used for a test, a sample is put in the full-automatic high-voltage test box, a test electrode of the sample can be subjected to automatic arrangement and withstand-voltage test through the control circuit, thus the system is simple in operation and is safe and reliable. Because a metal ball completely wraps on the outer surface of the sample to be tested under the action of the shape and the self-weight of the metal ball per se, the withstand-voltage performance of all surfaces of the sample to be tested can be measured to ensure that the test result is more accurate. Meanwhile, the metal ball can be recycled and repeatedly used, thus the test cost can be greatly reduced.

Description

technical field [0001] The present invention relates to a withstand voltage test system, in particular to an AC withstand voltage test system for various hand-held electric tools, instruments and meters, and household appliances, in particular to a handheld electric tool AC withstand voltage intelligent test system and its dedicated Fully automatic high pressure test chamber. Background technique [0002] Hand-held electric tools, instruments and household appliances need to meet GB 3883.1-2008 "Safety Part I of Handheld Electric Tools: General Requirements" and GB 4706.1-2005 "Safety Part I of Household and Similar Electrical Appliances: General Requirements" and other related Article requirements, especially the safety standards for electric strength of electrical appliances. The existing AC withstand voltage test method is relatively complicated and unreliable. For example, the electric strength test of the existing hand-held electric tools is to wrap a piece of metal f...

AI Technical Summary

Problems solved by technology

Because it is difficult to make complete contact between the metal foil and the surface of the test sample, there will always be small gaps in the local area, resulting in inaccurate test results and potential safety hazards

In addition, metal foil can only be used once and cannot be reused, and the cost of testing is high
