Product Description

GDYZ-50D Metal Oxide Arrester (with Series Gaps) Tester

Product Description

Power frequency discharge voltage is one of the important parameters reflecting the quality of electrical equipment. Zinc oxide arrester field tester (over-voltage protector tester) is an advanced intelligent test equipment designed according to the latest national power industry standard (JB/T6479-1992). It is widely used in 35kV and below power systems, mainly used for metal zinc oxide arrester (Electrical) with series gap components, insulating materials) and three-phase combined over-voltage protector are tested for power frequency discharge voltage and insulation strength to test the insulation level of the tested object, find the insulation defects of the tested object, and measure the over-voltage capacity. In the field acceptance and subsequent operation and maintenance, the power frequency discharge test of MOA-SG and TBP with series gap is an important and necessary work. The discharge voltage is an important parameter that directly reflects the product quality. If the test method of MOA without series gap is adopted to measure The measurement of power frequency discharge voltage of metal Zinc Oxide arrester with series gap will lead to high measurement results and misjudgment of equipment status. The Zinc Oxide arrester field tester (over-voltage protector tester) of our company is developed based on this. The tester consists of 2 parts: tester host and high-voltage test power supply. It is widely used in electrical manufacturing department, electric power operation Department and scientific research unit.

Features

• Equipped with 7-inch high-definition color LCD, PLC automatic electrical control.
• HV voltage, LV voltage and lLV current are isolated and collected synchronously. High precision sensor and high performance acquisition chip are used.
• The human-machine interface adopts full touch and partial key operation mode, intelligent working process, optional automatic mode and manual mode.
• The independent interface shows the HV voltage, LV voltage, LV current, time and withstand voltage results. The high voltage curve is displayed dynamically, and the display is intuitive.
• Perfect over-voltage, over-current protection, flashover protection, self-set output voltage, low-voltage current upper limit and timing time.
• With zero return detection function, the test can be carried out after automatic zero return, safe and reliable.
• It has 8000 pieces/3 months of local storage space and provides USB interface data export to external USB disk.
• Approximate voltage regulation algorithm, automatic voltage withstand timing after reaching the set voltage, and automatic step-down return to zero after timing.
• When the set low-voltage current is exceeded, the voltage output will be cut off automatically and the voltage will be reduced to zero. When the flashover protection value is exceeded, the voltage will be reduced to zero automatically.
• Software and hardware anti-interference design, a variety of anti-interference means, adapt to the harsh electromagnetic environment.
•  
• Automatic fault diagnosis, easy to find and solve problems, simple equipment maintenance, convenient maintenance.
