Dear user, you are very welcome to purchase our WJDS-20A standard source product. This product can generate three-phase power frequency voltage and current signals with adjustable amplitude, adjustable phase, adjustable frequency and stable power.

This product is an XC/TC type control box/set, which is a special supporting equipment for light test transformers produced by our company. It has the characteristics of easy use and maintenance, reliable performance, safety, beautiful appearance, durability, and light movement, and is an essential equipment for power supply, factories, metallurgy, power generation, railways and other power maintenance departments. At present, our company stipulates that less than 5kVA is the control box, and more than 5kVA is the console (the console model is TC).

The temperature rise test cart is a dedicated mobile test platform for temperature rise testing of electrical equipment (such as transformers, motors, reactors, etc.).

The reliable and effective connection of the grounding wire of power equipment is the fundamental guarantee to ensure the safe operation of maintenance personnel. The grounding wire is the connection between the power equipment and the ground network, and the primary task is to hang the grounding wire for power outage maintenance. Therefore, in the "Twenty-five Key Requirements for Preventing Major Accidents in Power Production", it is clearly stated that the conduction inspection of the down conductor of the grounding device should be carried out once a year. This grounding down conduction tester is a portable tester with a high degree of automation developed by our company, which is used to ensure the good conductivity of the ground wire for power outage maintenance in the substation. The instrument is controlled by a high-performance microcontroller, which can realize the intelligent testing process.

The comprehensive performance test bench of fully automatic transformer complies with relevant national standards such as GB/T4776, GB/T5169, GB/4285-1993 and other relevant national standards. This console mainly tests the no-load and load characteristics of power transformers and distribution transformers, and can also conduct induction and power frequency withstand voltage tests on the subject transformers. The measuring part of the device is controlled by a microcontroller, and the test data such as digital display, no load, short circuit are synchronously sampled by the microcontroller, avoiding the errors caused by the reading of voltage, ammeter, and power meter in traditional test methods and manual calculations.

For power systems, transformers are the core equipment in the system, so the long-term and reliable operation of the transformer is related to the stability and reliability of the entire system. The DC resistance of a transformer is a must-test project in the manufacturing of semi-finished products and finished products for factory tests, installation, handover tests and power department preventive tests. It can effectively discover manufacturing defects such as material selection, welding, loose connection parts, lack of strands, and broken wires of the transformer coil and hidden dangers after operation. In order to meet the needs of rapid measurement of DC resistance of transformers, our company has developed a DC resistance tester for transformers using its own technical advantages. This instrument is a new generation of rapid tester integrating magnetic assist method testing, three-phase testing (Yn, Y, △) and demagnetization functions. It is an ideal device for measuring the DC resistance of large power transformers. The screen uses a true color large screen high-resolution LCD display, touch and shuttle knob, for easy on-site use. It has Chinese menu prompt function, easy and intuitive operation, completes all direct resistance test items in one wiring, fast test speed, high accuracy and wide range.
