        Wenzhou Qiupu Electric Power Co., Ltd. is located in Yueqing Economic Development Zone, Zhejiang Province. It is a high-tech enterprise specializing in the research and development, production and sales of electric power products such as circuit breakers, transformers, power distribution switches and high and low voltage electrics. Our products are widely used in financial, communications, municipal, transportation, power, construction, aerospace, industrial control and other important areas, has won the majority of users praise and signed a long-term cooperation agreement.
        As an innovative technology-based enterprises, the company has strong technical force and the world's leading production technology and high-end testing equipment, and establish and improve the procurement of components, product processing assembly, testing, packaging to sell a complete set Quality management system to ensure that every product of the eligibility, the company has 10 years of experience in the power industry, and is still growing, product and sales network throughout the country.


        The interlock of high voltage switchgear is an important measure to ensure the safe operation of power network, ensure the safety of equipment and person and prevent misoperation. This is also clearly stipulated in GB3906, 3-35kV AC Metal Closed Switch Equipment. Generally describe the interlock as: prevent misdivision, Misfit circuit breaker: prevent load separation, close isolation switch; Prevent the connection line(ground switch): prevent the connection line(switch) closed circuit breaker, load switch: prevent the accidental electrical interval. The content of the above five items to prevent electrical misoperation is referred to as "five precautions". "Five-guard" devices can be generally divided into three categories: mechanical, electrical and integrated. At present, there are many types of high voltage switchgear in the market, most of which have a more perfect interlock mode. However, there are still a lot of high voltage switchgear interlocks, especially mechanical interlocks are not perfect, can not fully meet the "five defense" requirements. For this reason, this paper deals with the KYN28-12 type metal closed armored removable switching equipment which is widely used in power system.


       Middle cabinet, all known as metal armor in the case of a shift switch equipment. It is a high voltage distribution unit with a maximum operating voltage of 3.6 / 7.2 / 12kV and is an indoor distribution unit of a three-phase AC 50 Hz single bus segment system or a double bus segment system. It is used to receive and match the network electricity of 3.6-12kV, and to control, protect, monitor and measure the electric circuit. Medium type switchgear is mainly used for power plant, small and medium power generator, power substation of power system, power supply, power distribution of industrial and mining enterprises, and starting of large high voltage motor.

Zhongzhigui's full name is the Armoured Installed Switchgear, which moves the medium metal switch with a three-tier structure, with a bus and dashboard(isolated from each other), a circuit breaker room in the middle and a cable room in the lower. Because the circuit breaker is in the middle layer, so it is called the armor type to move the type of metal closed switch equipment, short for the cabinet.

Our Team

        KYN 28-12 as a three-phase exchange of 3.6-12kV indoor distribution unit 50Hz, due to the small size, compact structure, high level of protection, easy installation and maintenance, hand vehicle exchange, complete metal armor and complete separation, all operations can be carried out under the closure of the cabinet state, safe and reliable, and so on, the power system is widely used, playing an important role for modern grid construction.
