Voltage-withstanding insulation tester

Abstract

The invention discloses a voltage-withstanding insulation tester comprising a casing, a control switch, control buttons, a main switch, a round button, a display screen, a display lamp, a three-head joint, a safety button, a regulating transformer, a boosting transformer, joints, through holes, a voltage sampler, a time system, an alarm system, a wire, a controller, grooves, and a socket. The tester has the following beneficial effects: the tester is designed reasonably; the controller is connected with the boosting transformer by the wire and the voltage sampler, the time system, and the alarm system are connected successively inside the controller to realize data transform; the controller is suitable for different circuit connection; the tester is convenient to convert and utilize; the voltage withstanding function of the tester is realized; and the controller is arranged in the middle inside the casing and insulating materials are arranged on the outer surfaces of the casing and thecontroller, so that the tester casing has the good insulating effect and the safety of the tester is improved.

Description

technical field [0001] The invention relates to a withstand voltage device, in particular to a withstand voltage insulation tester. Background technique [0002] Voltage withstand insulation tester, also known as electrical insulation strength tester, or dielectric strength tester, also known as dielectric breakdown device, dielectric strength tester, high voltage tester, high voltage breakdown device, withstand voltage tester, etc., will be a It is stipulated that AC or DC high voltage is applied between the live part of the electrical appliance and the non-live part (usually the shell) to check the withstand voltage capability of the insulating material of the electrical appliance. In the long-term operation of the electrical appliance, it must not only withstand the rated working voltage , but also to withstand short-term overvoltages higher than the rated operating voltage during operation (the overvoltage value may be several times higher than the rated operating voltag...

[0002] Voltage withstand insulation tester, also known as electrical insulation strength tester, or dielectric strength tester, also known as dielectric breakdown device, dielectric strength tester, high voltage tester, high voltage breakdown device, withstand voltage tester, etc., will be a It is stipulated that AC or DC high voltage is applied between the live part of the electrical appliance and the non-live part (usually the shell) to check the withstand voltage capability of the insulating material of the electrical appliance. In the long-term operation of the electrical appliance, it must not only withstand the rated working voltage , but also to withstand short-term overvoltages higher than the rated operating voltage during operation (the overvoltage value may be several times higher than the rated operating voltage value), under the action of these voltages, the internal structure of the electrical insulation material There will be changes, the use of the withstand voltage insulation tester is not very good, there are great shortcomings, and most of the tester insulation effect is not good, it is easy to cause safety problems, therefore, in response to these problems, provide a withstand voltage insulation tester
