產品描述

yongsung韓國龍聲株式會社 >> 凸輪開關類/萬能轉換開關 >> 43pd motor cam switch 控制馬達凸輪開關(ysmc)

		43pd motor cam switch is equipment to supply electric voltage for control to protection relay, meter ,control
		power voltage, etc. due to automatic transference of bus in accordance with connection state of 2nd voltage
		of bus p.t in substation double bus structure. 43pd moter cam switch protects occurring malfunction
		of equipment in case of manual transference of 2nd voltage.
		this equipment applies for auto-control and scada of efficient application of total protection control system.

		＊ applying place of protection relay ＊ - protection panel for t/l railway line) - protection panel for bus) - protection panel for u.f.r) - system voltage of requiring transference of p.t) - protection panel for m.tr 154/23kv)

contact rating	250v, 20a
maximum rating voltage	600v
dc open-close volume	dc 125v, 20a (50ms)
control power voltage	dc 125v (range of using voltage : dc94v ~ dc 156v)
operating electric current	below 1.0a
transference speed	after inputting external signal, bus is changed a -> b or b ->a transference time of p.t voltage perfectly is within 2.5sec. in case of supplying rating control voltage dc 125v
time of transference current	after operating switch, bus is changed a -> b or b ->a transference time of no p.t voltage perfectly is within 2.5sec. in case of supplying rating control voltage dc 125v
insulation resistance	above 50m ＆#8486;
mechanical life time	above 200,000 times (after operating 1 time, equipment is stopped 5 seconds)

manual control

		in case of field test or manual operation requested, pull the handle at pull-out position (manual
		operation position) then enable to operate manually
		enable to do manual control regardless of contact position of related aux-s/w for remote signal
		lighting green led lamp using for indicating manual operating position)
		pushing the handle forward at pull-in position (automatic operating position) then led lamp is
		changed to red lighting and operated as automatic control

automatic control

		using it connected with bus aux-s/w contact as below 43pd connection diagram (drawing1)
		when bus aux-s/w is transferred then transferred automatically to (a-b bus) appropriate bus(b bus)
		unable to operate at bridge position where bus aux-s/w putted into simultaneously and enable to
		operate as bus aux-s/w transference completed.
		operated automatically only at pull-in position (automatic operating position) pushing front handle forward

remote control

		using contact of remote control after connecting as below 43pd connection diagram (drawing2)
		remote control signal uses three contacts such as a-bus, b-bus, off)
		enable to operate at automatic control position (pull-in position) and unable to operate at manual
		control position (pull-out position).

automatic/remote control

		using it connected as below 43pd connection diagram (drawing3))
		motion form of automatic control is same as motion form of remote control)

built-in remote control method

		pull in the cam switch handle then supply control power voltage to 19 and 20 terminal. at this moment,
		check whether green color of led is changed to red color of led pushing handle out after lighting
		confirmed)
		check remote control pushing handle in center as off position)
		check whether the switch handle moves into b-bus when supplying dc+ to no.5 terminal block of cam
		switch)
		check whether the switch handle moves into a-bus when supplying dc+ to no.7 terminal of cam switch)
		check whether the switch handle moves into center position (off) when supplying dc+ to no.9
		terminal of cam switch.

	¡ø note
	1. contact composition of dc lock is possible to be different according to 43pd model
	2. 43pd contact composition is basic contact composition
	3. it is able to operate manual control and field test only in case of pulling front handle out
