1、Summary The main part of 10kV switchgear includes：vacuum circuit breaker、current transformer、On-site installation of microcomputer protection device、Operating circuit accessories（handle、indicator light、pressing plate and so on）、A variety of locations of auxiliary switch.Thereinto,circuit breaker and current transformer are installed in the switchgear,Microcomputer Protection、Attachment、watt hour meter are installed in the relay room（Continue as before， there is no relay actually）on the panel,terminal board and all kinds of power supply air switch are installed in a relay interior ministry，Terminal row through the control cable or special socket to connect the circuit breaker mechanism. TO understand the secondary wiring of switchgear,we need to find two drawings：since protection principle diagram、wiring diagram provided by the manufacturer；Secondary principle diagram、wiring diagram、terminal strip diagram、principle diagram of the circuit breaker mechanism provided by the switchgear manufacturer. 2、10kV cable line in the cupboard KYN28A（GZS1）Centrally Installed Switchgear is 10 kv switch cabinet type used by the most urban substation，from a positive perspective，It obviously divides into three parts，topside is relay room,middle is circuit breaker chamber,underside is an empty room（Nothing），Bus and other high pressure equipment is mounted in the back of the cabinet put oneself in another’s position.As shown in the figure below.   Read More >>
