1, An overview of the
1.1 KYNl8A - 12 indoor communication armoured move open metal-enclosed
switchgear (hereinafter referred to as the switch cabinet).Of type of vacuum
switchgear, vacuum switch mainly choose ZN22B - 12 vacuum circuit breaker,
can also with ZNl2-10 3 of the vacuum circuit breaker and Siemens af, 3 ah
vacuum circuit breaker.
1.2 this product conforms to the GB3906-91 "3-35 kv ac metal-enclosed
switchgear" DL404-91 "indoor communication switch cabinet order technical
conditions" and IEC298 ac metal-enclosed switchgear and control equipment,
such as standard.Suitable for 3 to 10 kv ac three-phase 50 hz single busbar in
the power system for receiving and distribution of electrical energy.Can be
widely used in various types of power plants, substations, and industrial and
mining enterprises.This product is reliable installation (not recommended) and without walls.
4, can be removed parts
4.1 can remove the components within the switchgear.
4.4.1 positioning: positioning state can be removed parts inside ark of a stable
state, when in this state, can remove the components of the circuit breaker
can be installed on closing or break-brake operations;Feed mechanism of crank
pin was closed, can remove the parts can't move.Conditions for remove the
positioning of parts in the work location and test (store) position only.The
realization of the positioning state and lifted, are achieved by the rotation of
the key chain. Place in positioning, key chain can be pulled out.
4.1.2 mobile status: mobile state can be removed parts inside ark of a temporary
state.In this state, can remove the components are installed on the circuit breaker
can not operate, feed mechanism crank pin open, can be removed parts in the enclosure
movement between test position and work location.At this point, the key chain can't pull out.
4.2 to move the location of the components in the switch cabinet.
2 work location: this is to remove the components inside ark of a state of positioning.
In the work place, switchgear on the main circuit, auxiliary circuit is switched on.
4.2.2 test position: this is can be removed parts inside ark of a state of positioning.
In the test position, switch cabinet on the secondary circuit, but the primary loop disconnect,
and dynamic and static contact is separated by metal curtain plate.
Holdings store location: if can remove the components inside ark test position again to cut off
the auxiliary circuit, can remove the parts is in storage location.
