The test equipment of simulating pulse high voltage is mainly used to carry out impulse voltage test of full impulse voltage wave, truncated impulse voltage wave and operational impulse voltage wave of electric power equipment, and check the insulation pe
The products are mainly used in transformer ratio group test, PT, CT ratio polarity test, the test speed is fast, high accuracy.
Suitable for all kinds of household appliances, power switches, wires and cables, transformers, terminal terminals, high voltage bakelite electrical appliances, motors, medical, chemical, instrumentation, etc., as well as the safety of the strong current system voltage and leakage current testing, but also scientific research laboratories, technical supervision departments indispensable voltage test equipment.
It is mainly used for primary busbar protection and the ratio and polarity of various current transformers, as well as the operation time of primary current test of power system, and is widely used in scientific research, production and electrical test sites of electric power, railway, petrochemical, metallurgy and mining enterprises.
The instrument is controlled by a micro-chip computer, which can automatically complete a series of operations such as static discharge, pressure boost, stirring, calculating average value, displaying data, storing data, printing, and measuring the temperature and humidity at that time. Oil pressure cycle test can be carried out in the range of 0-80kV.
Dc resistance of transformer is a must-test item of semi-finished product, finished product factory test, installation, handover test and preventive test of power department in transformer manufacturing, which can effectively find manufacturing defects such as material selection, welding, loose connection parts, missing strands, broken wires and other hidden dangers after operation.
KDWS-2500A intelligent DC high-current generator (DC high-current source) User basis: Used for continuous current-carrying temperature rise, current-carrying current and current cycle test of current-carrying conductive products in electrified railway and urban rail transit power supply products.
Suitable for 66KV and above voltage grade power transformers, and other special purpose transformers.
The instrument can accurately measure the power frequency parameters (positive sequence capacitance, zero sequence capacitance, positive sequence impedance, zero sequence impedance, mutual inductance and coupling capacitance, interphase capacitance, etc.) of various high-voltage transmission lines (overhead, cable, overhead cable mix, and multiple sets of the same pole).
Used to test the continuity of paint film of enamelled round wire with nominal diameter of 0.050mm or above and 1.600mm or below (i.e. the number of pinholes per unit length of enamelled wire sample).
It is suitable for measuring the speed of switches produced by switch factories at home and abroad.
In addition to measuring ground resistance, low resistance conductor resistance, soil resistivity and alternating current voltage can also be measured.
