■ Product profile
KYN28 Metal clad central removable switchgear cabinet(hereinafter referred to as switchgear)is a three-phase AC 50Hz indoor distribution device,which is used to receive and distribute 3-12kV network power and to control,protect and monitor the circuit.The relay chamber panel of the product can install various types of computer-based integrated relay protection devices,and can realize the intelligent control of the system,which has the functions of remote control,remote measurement,remote communication and remote adjustment.It controls the field network through communication interface CAN,and has“Five Electric Preventions”functions of preventing misoperation of circuit breakers,preventing loaded push-pull handcarts,preventing charged switching off ground switches,preventing power transmission of ground switch in the ground position and preventing mislead charging interval.The cabinet can be equipped with VSI(ZN63)and ZN12V vacuum circuit breakers,as well as can be equipped with imported VD4 vacuum circuit breakers and VC series vacuum contactors.

■ Product features
● The cabinet body adopts the assembling structure,which is connected by the rivet nut and the high-strength bolt,so that the processing and production cycle is short,the spare parts are universal,the floor area is small,and it is easy to organize production.
 
● The handcart has disconnection position,test position and working position in the cabinet,and each position has a positioning device respectively to ensure the reliability of the interlocking.It must be operated according to the interlocking anti-misoperation procedure.
 
● The main electrical components of the switchgear have their own compartment,that is breaker handcart room,bus-bar room,cable room,relay instrument room.The protection level of each compartment shall reach IP2X.
 
● The switchgear is equipped with safe and reliable interlocking device,which fully meets the requirements of"five electric prevention".
 
● Pressure reliefs are set above the breaker handcart room,bus-bar room and cable room.When the inner fault air pressure rises,the special sealing ring installed on the door will seal the front.The pressure relief metal plate of the device will be opened automatically.Release pressure and gas to ensure the safety of operator and switchgear.
 
● The secondary plug can be plugged in and released only when the circuit breaker handcart is in the test and disconnection position.Because the closing mechanism of the breaker handcart is locked by electromagnet,the breaker handcart can only be opened before the secondary plug is not connected,and can’t be closed.
 
● The switchgear can be equipped with live display device,which can not only prompt the power status of high-pressure circuit,but also cooperate with electromagnetic lock to realize the forced locking of grounding switch handle and mesh door etc.,so as to improve the anti-misoperation performance of supporting products.
 
● In order to prevent the risk of condensation in climate,heaters are installed in the circuit breaker room and cable room respectively to prevent condensation and corrosion in the above environment.
 
● 6*40mm grounding copper bar is separately set in the cable room,which can run through the adjacent switchgear,and is in good contact with the cabinet.The copper bar is used for the direct grounding of element.
