Product overview It is applicable for monitoring the SF6 gas density in a sealed vessel. It can show gas density values on the site. When the gas density reaches the preset value, the contact-making device will send alarm and control signals. It can be widely used in electric equipment including SF6-insulated composite apparatus, circuit breakers, pole-mounted switches, transformers and mutual inductors.It provides solutions for new construction of transformer substations and intelligent reconstruction of existing transformer substations.
Product Features
1. Electric contact switch design realizes accurate and reliable SF6 gas monitoring functions. 2. With temperature compensation, the compensation performance is stable and the detection precision is high. 3. On-site display values and output contact signals are not affected by external conditions including the altitude and ambient temperature change. 4. Core elements are made of imported materials with high precision. 5. Good shockproof performance. 6. There are three contact groups at most, which can realize several options including overpressure alarm, double alarm or double lock and make the monitoring safer and more reliable. 7.Gas fill, micro-water test and calibration can be implemented without removal of the SF6 gas density relay, making it easy for on-site staff to conduct micro-water test and gas supplementand avoiding the seal face and seal ring damage arising from removal. 8.304 stainless steel is adopted for the sealed case, which prevents both moisture and corrosion.
Company Profile
Wuxi Kaifeng Pressure Gauge Co., Ltd, founded in 2004, is a company specialized in the modern scale production of ressure gauges. It is locate by the scenic Taihu Lake in the developed Yangtze River Delta region of China. Since its establishment, Kaifeng has been ontinuously expanding its size, increasing equipment, improving testing methods and introducing new technologies and new processes. It has now become a manufacturer focused on mid-range and high-end pressure gauges.We mainly provide supporting products for the firefighting system, life saving equipment, machine manufacture equipment, metallurgical, chemical, oil, food, medical, water treatment ad hydraulic systems.
It set up the subsidiary of Wuxi Kaifeng Electric Technology Co., Ltd. in 2017. According to market needs and its own product portfolio, the company has introduced advanced technologies and processes from home and abroad, made continuous innovations and developed the new generation SF6 gas density relays, density meters and pressure gauges based on its original pressure gauge products. The new products achieve better performance, reliability and safety and provide high quality in the SF6 gas density monitoring area with more precision, sensitiveness, contact reliability, shock resistance and steady performance.
The company has built up a rigorous and comprehensive production quality supervision and management system. It passed 1SO9001 system certification in 2008 and EU ECE certification in 2015. Besides, it has also obtained a dozen of patents.Over recent years, all employees of the company, from top to bottom, have been working hard together. As a result, the company has seen considerable development along with greater overall strength and development potential. In future, we will always stick to the guiding philosophy of “Only development is the cardinal principle” , maintain the mature manufacture process and good-faith operation guided by advanced development concepts, and make more innovations and developments in teamwork spirit. We will cut through wind and waves of the fierce market competition on the path towards building up the company into the No.1 pressure gauge brand in China as well as a global leading expert of total solutions for gas monitoring in the power industry.
