Terminal detector detects the terminal has provided more versatile instrument Rally European standard, European standard instrument universal testing machine, tensile stress respect for terminals connected test analysis and robustness condition. European standard instrument Rally endurance test terminals can be easily and stress deformation. Terminals gradually widely applied to various fields, in terms of passing electrical and conductive connections played a role in reducing the consumption of the workload and cost of production, to the production and use has brought a lot of convenience, to avoid a lot of trouble. So as to simplify the product structure, the purpose of manufacturing cost savings. So bring benefits for the terminal to detect and combined with market analysis, recommended for terminal testing instrument professional testing equipment for testing. Common terminal testing equipment: microscope and optical imaging instrument. Voltage transformer is a voltage conversion device. It is converted to low-voltage high-voltage line socket terminals in order to reflect changes in the magnitude of the high pressure with low pressure values. Thus, by measuring the voltage transformer voltage can be directly used ordinary electrical instrumentation. As a result of voltage transformers, various measuring instruments and protective devices are not directly connected to the high voltage meter to measure in order to ensure the safety and protection work, but also to solve the difficulties of high voltage insulation measuring manufacturing processes. In addition, since the secondary side voltage transformers are 10 volts makes measuring instruments and relay coil voltage to standardize manufacturing. Structure and working principle of common transformer voltage transformer with the same, it is also the core, primary winding, secondary winding, terminals and insulation support and other components. Voltage transformer primary winding is connected to the system line voltage or phase voltage insulation should vary with the actual system voltage level may be. The primary winding has more turns double play ends 1.25 refractory IC, secondary winding turns rarely supply voltage meter or relay coil. Do not allow the voltage transformer secondary winding is shorted. Secondary winding 10 volts, should be connected to be able to withstand 10 volt circuit in purchasing terminal harness, which passed current from the secondary circuit impedance to determine the size. The secondary is shorted, the impedance is very small, the current flowing through the secondary circuit is increased, resulting in secondary fuse blown impact protection meter indication and cause malfunction, damage to the voltage transformer. Voltage transformer secondary circuit must be grounded to prevent a secondary breakdown of high voltage insulation damage to the secondary side of the string to be hazardous to personnel and equipment.
