YKG-5013C Vehicle High Voltage Switch Tester
First, instrument introduction
The high-voltage switch tester is the latest special test instrument developed by our company to meet the needs of on-site testing of high-voltage switch mechanical characteristics and other parameters, and is based on the new technology standard of high-voltage switch dynamic characteristics tester. The instrument takes the single-chip microcomputer as the core and adopts the CPLD storage drum sampling technology. Its main feature is the use of a rotary sensor, the sensor is easy to install, the test accuracy is high, and one machine is used more. It adopts Chinese large-screen liquid crystal display test results and can print out test curves and test parameters. It has the advantages of intelligence, multiple functions, accurate data, strong anti-interference, simple operation, small size, light weight, and beautiful appearance. A variety of indoor, outdoor, less oil, oil switch, vacuum switch, sulfur hexafluoride switch test.
The tester is an embedded structure and can be installed in a cabinet. The chassis is a standard 3U/4U chassis with a computer interface, provides test data and transmission protocols, and can collect data on-board.

Sunket has launched HJT solar modules, which have the following 10 advantages:
1) Higher conversion efficiency: higher installed capacity within a limited installation area and lower BOS cost;
2) Higher reliability: Our product design is mature and has been tested by the market. Compared with large-sized components, it is more effective in resisting wind load and snow pressure, and it is not easy to cause frame damage, glass burst, and a large number of hidden cracks to cause excessive attenuation of components. ;
3) Low attenuation rate: 90% power line quality guarantee is still available after 30 years of use;
4) Low temperature coefficient of -0.24%: 2%-3.9% higher power generation per watt compared to conventional PERC;
5) Better low-light power generation performance: HJT adopts N-type silicon wafer technology, which generates 1% more electricity per watt compared to single crystal PERC;
6) No PID, no LID attenuation: lower attenuation of components in the whole life cycle and higher power generation;
7) Double-sided rate as high as 90%+: the backside of our heterojunction modules can have more than 90% and at least 423W of backside power generation, and the power generation superposition is higher after double-sided installation;
8) Lower LCOE: At present, compared with PERC single crystal technology, our heterojunction technology is more advanced, achieving the lowest LCOE of power generation, faster payback period and maximum benefit;
9) Good matching: suitable for photovoltaic grid-connected inverters and photovoltaic tracking brackets used in domestic mainstream;
10) Cost-effective.
