Responsible after-sales service of HUAYI
Tongwei Tianmen Lake 250MW fish-light integrated photovoltaic power station project is one of the 59 key energy storage projects in Hubei Province in 2022, which has a very important role. The project is located in Tianmen City, Hubei Province. It is a fish-light complementary project.オン 4月 21, our company received a phone call from the customer. In order to ensure the progress of equipment maintenance and test, we invited our technical personnel to the site for technical guidance and exchange.残念なことに, from the 21st, the entire Hubei Province has a large area of heavy rain, in line with the original principle of all for the sake of customers, our company's after-sales service team immediately rectify and set out, even if the wind in the rain also dare not have a trace of delay.
テスト プロジェクト that the customer needs to cooperate with is the AC voltage withstand test of the ultra-long cable, the length of the cable is nearly eight kilometers, connected to the equipment between the various phase changes and boost stations.後 到着 at the project in the morning, the day began to rain heavily, because it is a high pressure test, the weather requirements are still relatively high, so the technical staff in the project department while developing the test plan, while waiting for the rain to stop, but the day is not satisfactory, the rain does not mean to stop. In order to ensure the normal progress of the project, we decided to set up the canopy after deliberation, and carried out ultra-low frequency voltage test on the long cable in the canopy. Say dry dry, frame canopy, code equipment, wiring, account for various test details, everything in the rain in an orderly way.
Through the effort of the customer's engineering construction staff and the company's technical staff, the test content of the entire project was finally completed at more than 4 o 'clock in the morning. It has made great contributions to the successful completion of the whole project, and has also been unanimously recognized by the client and the project party of Party A.
The equipment used in this project is cable voltage withstand equipment, which is mainly divided into AC voltage withstand equipment and DC voltage withstand equipment. Ac voltage withstand equipment is divided into series resonance voltage withstand device and ultra-low frequency voltage withstand device.XZB-D cable AC voltage series resonant device adopts the mode of adjusting the frequency of the power supply, so that the reactor and the tested capacitor achieve resonance, and obtain high voltage and high current on the tested product, which is a new method and power flow of the current high voltage test.It has been widely used at home and abroad. The portable cable voltage test device is composed of variable frequency power supply, excitation transformer, reactor and capacitive voltage divider. The capacitor and reactor of the tested product form a series resonance. Connection mode; The voltage divider is connected in parallel with the test object to measure the resonant voltage on the test object and act as the overvoltage protection signal; The frequency-modulated power output is coupled to the series resonant circuit through the excitation transformer to provide the series resonant excitation power.
周波数 変換 シリーズ 共振 テスト デバイス 使用 原理 の シリーズ 共振, uses 励起 変圧器 に 励起 変圧器 に 励起 直列 共鳴 回路, 調整 出力 周波数 of 周波数 変換 コントローラ, so that the loop インダクタ L 共振 in series with the test product C, and the resonance voltage is the voltage added to the test product。 周波数 変換 共振 テスト デバイス は 広く 使用 で 電気 電力, 冶金, 石油, 化学 and other industries, suitable for large capacity, high voltage capacitive test and preventive test。
VLF hipot generator is a high voltage test device for ultra-low frequency AC resiststand voltage test. The device is suitable for the electric power department and industrial and mining enterprises to carry out insulation withstand voltage test for polyethylene, crosslinked polyethylene plastic cable and other high voltage electrical equipment on site. The device is less destructive than the DC resiststand voltage test and is equivalent to the AC 電源 周波数 耐電圧 電圧。
After a night of hard work, finally completed the set test goal. On the way back, the wind and rain are still heavy, and the after-sales staff is still tired and tired, but the heart of the after-sales staff is excited, for customer service, every action is worth it.
