Description
Technical Field
The utility model relates to an automatic monitoring devices of withstand voltage resistance belongs to automation equipment technical field.
Background
The resistance presented to the conductors is called the contact resistance. Contact resistance below 10-20mohm is generally required. Some switches are required to be below 100 and 500 uohm. Some circuits are sensitive to changes in contact resistance. It should be noted that the contact resistance of the switch is the maximum value of the allowed contact resistance of the switch over several contacts.
The circuit board is the contact point between the finger and the connector, and the resistance is the resistance when the current passes through. To reduce the formation of metal surface oxides, the positive gold finger portions and the negative clip of the connector are typically plated with metal to inhibit the occurrence of "loading resistance". The plug of other electrical appliances is squeezed into the socket, or the contact resistance exists between the guide pin and the connecting seat.
The voltage endurance tester is also called an electrical insulation strength tester or a dielectric strength tester, and also called a dielectric breakdown device, an insulation strength tester, a high voltage breakdown device, a voltage endurance tester and the like. A test in which a specified ac or dc high voltage is applied between a live part and a non-live part (generally, a case) of an electrical appliance to examine the withstand voltage capability of an insulating material of the electrical appliance. During long-term operation, the electrical appliance is subjected to not only the action of the rated operating voltage, but also the action of an overvoltage which is higher than the rated operating voltage and causes a short time 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 electrically insulating material will change. When the overvoltage strength reaches a certain value, the insulation of the material is broken down, the electric appliance cannot normally operate, and an operator can get an electric shock to endanger the personal safety. The main test indexes of electrical safety include alternating current/direct current withstand voltage, insulation resistance, leakage current, grounding resistance and the like. The alternating current/direct current withstand voltage test is used for testing the electrical safety performance of a product in an actual working state and is one of important indexes for testing the electrical safety performance of equipment.
The existing pressure-resistant tester in the market adopts GB4706 (equivalent IEC1010) standard, uses a single test index tester with a table structure, and cannot meet the requirement of a user on multi-index comprehensive test; moreover, most of the voltage endurance testers in the current market adopt the traditional testing method, the testing precision is not high, the adopted technology and the main performance indexes have certain differences from the foreign advanced level, and the requirements of the current developed electrical safety performance testing work cannot be completely met. Therefore, it is of great significance to research a voltage withstanding test system which meets the latest international standard and adopts advanced technology and has better performance indexes.
The voltage-resistant tester is mainly used for voltage-resistant testing of polyethylene-insulated power cables and also can be used for voltage-resistant insulation testing of large-scale power transformers. The voltage-resistant tester adopts an ultra-low frequency high voltage test method to test the voltage resistance of the power cable, which is a new method.
