Product Description

KYN28-12 Medium Voltage Switchgear

 

 

KYN28-12 (GZS1) indoor metal-fitted mid-shift open type switchgear (hereinafter referred to as the switch cabinet) is a three-phase ac 50Hz indoor power distribution unit, which is used to receive and distribute 3-12kv network power and to control, protect and monitor the circuit.The product can be installed on the panel of the relay chamber of various types of microcomputer type integrated relay protection devices, and can achieve intelligent control of the system, with remote control, telemetry, remote communication and remote control functions, can bus with communication interface to control the field network.It also has the function of preventing the wrong operation of the circuit breaker, preventing the trolley from pushing and pulling with load, preventing the electrifying closing grounding switch, preventing the grounding switch from sending electricity at the grounding position and preventing the electrifying interval from entering by mistake, which is referred to as "five defense".

 

AC metal closed type shift switch cabinet is a three-phase ac 50HZ indoor device metal closed switch equipment. Is used in power plants, substation system rated voltage 35kV, rated maximum current 2000A maximum voltage no more than 40.5kV single bus or single bus sectionalized sets of distribution equipment.
This switch device meets the requirements of DL/ t404-91, IEC298, GB3906 and other standards, and has the functions of preventing wrong operation of circuit breaker, pushing and pulling handcart with load, grounding line, power transmission with grounding line and accidental charging interval (referred to as "five precautions").

 

Structural Features

Kyn28-12 metal-armored high voltage switchgear adopts intermediate structure, which saves about 50% of the circuit breaker room and facilitates cable installation.The primary circuit switch is installed on the kola car, which is easy to be interchanged with the size trolley.Due to the armored construction, the components are installed in an earthing compartment separated by a metal partition.The protection grade of switch cabinet is IP4X.Vacuum circuit breaker with permanent magnet mechanism can be equipped with vacuum circuit breaker VS1, VD4, ZN63, etc.The switch cabinet can be connected with the protection system, with the function of "four remote control", realizing the automation of the distribution station.
