KYN28A type indoor AC metal armored away Switchgear 
 I. Overview 
 KYN28A type indoor AC metal armored away Switchgear Series 3-12kV rated voltage three-phase AC 50Hz single bus and single bus system, power distribution equipment segment. Transmission for power plants, electrical substations by electrical systems, and industrial and mining enterprises, power distribution and high voltage motor starting, etc., to achieve control, protection, detection purposes. 
 The switch cabinet can meet GB3906, IEC298 and other standard requirements, and has a circuit breaker to prevent misuse, to prevent negative Hela Used to prevent the charged closing ground switch, to prevent the grounding switch position in the ground to prevent straying into electric power transmission and isolation, " Five Protection "feature. Switchgear is equipped with both VD4 vacuum circuit breaker ABB company, but also with use my homemade VS1 vacuum circuit breaker, in fact, a distribution device of superior performance. 
 Second, the main features 
 ? cabinet structure with deposited aluminum zinc plate bending by CNC machine process using multiple bolted together after processing; 
 ? All operations are carried out under the door closed; 
 ? high degree of protection to prevent debris and pest invasion; 
 ? simple and effective "Five Anti" lock to prevent misuse; 
 ? can be equipped with VS1 and VD4 type vacuum circuit breaker; 
 ? Replace the circuit is simple, Used good interchangeability; 
 ? cabinet can be installed against a wall, cabinet before the maintenance, reduce floor space; 
 ? ample cable room space, multiple cables can be connected; 
 Circuit breaker room and cable room install the heater, respectively, to prevent condensation and corrosion occurs. 
 Third, the structure shows 
 Switchgear cabinet and by the fixed part can be extracted (Used) composed of two parts. Cabinet housing and the functional units of the partition are used dressing made of aluminum and zinc plate bolted. Switchgear enclosure protection grade IP4X, each compartment of the protection class IP2X. Switch cabinet with overhead inlet and outlet, around the cable into the outlet and the liaison function, the program can use the arrangement of the switch cabinet formed to complete the design features of the distribution device. 
 The installation and commissioning of the switchgear can be a positive basis, either against a wall to save floor space, reduce investment.
