The KYN58-12 metal armored removable switch equipment is a new concept switch cabinet developed by Wuhan Changxing Electric Appliance Development Co., Ltd., which conforms to GB, lEC, DlN and other standards, and is suitable for different types of substations, power plants, industrial and mining enterprises and high-rise buildings. The switchgear is particularly suitable for frequent operation. The friendly man-machine interface makes the switchgear operation programmed and formulaic, and the operator can see at a glance. The unique design of the propulsion mechanism enables the handcart to automatically locate the position during the propulsion and launch process, and the contact of the isolated contact is more reliable. The tool handcart with adjustable upper and lower lifting width can easily put different types of handcarts on the ground or working platform for maintenance. The tool handcart and the switch cabinet are equipped with reliable locking, which strengthens the anti-falling measures of the handcart. If the tool handcart is not reliably engaged with the cabinet, the handcart cannot be pushed into the cabinet or pulled out from the cabinet. CT installation is changed from vertical installation after cabinet to hoisting, which increases the space of cable room, and the cable connection height is more than 800mm, making cable installation convenient and maintenance simple. The secondary plug is fully latched. The grounding interlock is simple and reliable. The combined valve is flexible to open. With the pull-out of the circuit breaker, the valve is automatically closed and forced to lock, eliminating the danger of accidentally touching high-voltage electricity. The four-pin lock door structure relieves the usual trouble of closing and opening the door. No matter what state, the solid and reliable door can effectively withstand the impact of internal fault arc. The door of the circuit breaker chamber and the circuit breaker have reliable interlocking. Only when the door of the circuit breaker chamber is closed can the circuit breaker be operated, which effectively prevents the arc from harming people when the fault is closed. Sturdy cabinet, effective pressure release channel can withstand internal fault arc impact and burning, effectively protect the operator's personal safety. Reasonable electric field distribution and insulation structure design make the switch cabinet insulation reliable and meet the requirements of all working conditions (the cabinet has passed the condensation and pollution test). Normal use environment conditions ● Ambient temperature:-25 ℃ ~ 45 ℃; ● Altitude: not more than 1000m; ● Relative temperature: not more than 90%( 25 ℃); ● Earthquake intensity: not more than 8 degrees; ● No fire, explosion hazard, serious pollution, chemical corrosion and severe vibration.
