Low-voltage switchgear power-on test bench for high and low voltage switchgear manufacturers High-low voltage switchgear power supply test bench Various high-voltage switchgear produced before the factory's power test. It can provide a variety of AC and DC power supply to facilitate the detection of switchgear and improve work efficiency. The low-voltage switchgear power-on test bench is simple and easy to use, and the power loop resistance test can be powerful and multi-output. Try to select the appropriate range of torque meter. If the tested motor has more specifications, it is necessary to use more than one torque meter to use with the motor. The synchronous test of the power and mechanical power of the low-voltage switchgear power-on test bench is performed. The electric power test of the power test system is synchronized with the torque and the speed as much as possible. The synchronization test here is not the same as the simultaneous test (or simultaneous recording). The synchronization test is equivalent to the same start point and the same end point for each measured data.
In general, if the two systems of the low-voltage switchgear power-on test stand are not manufactured by one manufacturer, it is difficult to achieve this function. This point needs to be addressed to integrators. It is recommended to use AnyWay's WP4000 frequency conversion power analyzer, which can not only meet the electrical power measurement requirements, but also extend the synchronous measurement of torque and rotation speed. The low-voltage switchgear power-on test bench is mainly applicable to the DC power endurance test or DC leakage current test of high-voltage electrical equipment such as zinc oxide arresters, power cables, transformers, circuit breakers, and generators in the power departments of the power sector, mining, metallurgy, and iron and steel enterprises. . The low-voltage switchgear power-on test bench adopts a portable chassis, which is portable and uses TPPWM technology to adjust the PWM inaccuracy linearity, and the accuracy is greatly improved. Ripple coefficient ≤ 0.2%, automatic zinc oxide surge arrester and oil-immersed transformer measurement function, you can directly print the experimental report and save the experimental report.
Low-voltage switchgear power-on test bench with total time T1 and subsection time T2, and any voltage, current print function, add the calendar and time functions, experimental report with time and date, but also for a variety of low-voltage electronics, instrumentation Power transformers, inductor coils, and electrical coils are used for double-frequency voltage doubler tests. They can also be used as power supplies or tests for certain special electrical equipment as multiplication power supplies with a power no greater than 1 kW. Low-voltage switchgear power-on test bench is static frequency conversion equipment, low noise, small size, can replace the traditional frequency conversion unit in high-voltage systems, the primary side connected into a star, the secondary side connected into an open triangle, plus a symmetrical side When the three-phase sine wave power supply is used, and the voltage is increased to saturate the core magnetic circuit, the magnetic flux contained in the third harmonic component increases, and the corresponding third harmonic voltage on the core coil also increases. The low-voltage switchgear power-on test bench is powered by a 150-Hz (three-times power-frequency) induced voltage output from the secondary side of the open delta generator as the triple-frequency test power supply voltage.
Low-voltage switchgear power-on test bench has the advantage of automatic control
Low-voltage switchgear power-on test bench adopts new technology to set overvoltage protection and overcurrent protection instead of digital dial switch. Only the voltage value can be set, and the problem of current value and voltage drift cannot be set. It is a power system, a power plant, a substation. One of the basic equipment for frequency-multiplier induction high-voltage testing of small-capacity power transformers and cascade-type high-voltage voltage transformers in power supply and distribution networks.
