It should be noted that inlet wire connection sheet 10 is pulled on the right side of switching device by the first tension spring 40, at this time under normality
Inlet wire connection sheet 10 is not connected to outlet connection sheet 80, and circuit is in an off state.
When bus bar side disconnecting link closure when, direct current signal route electrification, closing coil 70 be powered be attracted combined floodgate armature 60 to
It pulls inlet wire connection sheet 10 to run to the left, executes feed motion.
Upper and lower two groups of outlet connection sheets 80 can refer to Fig. 3, i.e. first group of bus-bar potential transformer is secondary with the connection that is in parallel
Line A1, B1, C1 phase are corresponding with second group of bus-bar potential transformer secondary line A2, B2, C2 to be connected in parallel: A1-A2, B1-B2,
C1-C2。
Under normality, outlet connection sheet 80 is remained fixed in support shaft 120 by the second tension spring 110, outlet connection sheet
80 are kept with inlet wire connection sheet 10 by the axle center of shaft seat 100 and support shaft 120 in same level direction.
The outlet connection sheet 80 of A phase, B phase, C phase is fixed with the second insulation board, realizes the synchronous fortune of three-phase outlet connection sheet 80
It is dynamic, disconnected when this circuit correspond to bus bar side disconnecting link, direct current signal route decompression and another bus bar side disconnecting link close make it is another directly
When flowing the electrification of signal line route, magnetictrip iron core 150, which is powered, is attracted tripping armature 140, and outlet side contact pin at this time is to turn
100 axle center of axle bed is that the center of circle rotates to thread off with inlet wire connection sheet 10 to far from 120 direction of support shaft.Inlet wire connection sheet 10 exists
It is resetted under the pulling of first tension spring 40, off voltage circuit.
In the present embodiment, travel switch uses Direct Action Type travel switch, includes Direct Action Type travel switch break contact 180
And Direct Action Type travel switch moving together contact 160.It remains turned on, accesses under 180 normality of Direct Action Type travel switch break contact
The electric power loop of the closing coil 70 of secondary circuit feed motion is executed, is protected under 160 normality of Direct Action Type travel switch moving together contact
Off-state is held, access executes the electric power loop of the magnetictrip iron core 150 of trip action.
In the present embodiment, the power supply of closing coil 70 is local terminal bus disconnecting link direct current signal power supply, and bus disconnecting link closes
Direct current signal route charges afterwards, and Direct Action Type travel switch break contact 180 is in closed state, and closing coil 70 powers on suction
Closing combined floodgate armature 60 pulls inlet wire connection sheet 10 and outlet connection sheet 80 to close a floodgate.Direct Action Type travel switch break contact 180 into
Collision first insulation fixing plate 50 before line connection sheet 10 and outlet connection sheet 80 are closed a floodgate completely, keeps Direct Action Type travel switch dynamic
Disconnected contact 180 disconnects 70 electric power loop of closing coil, and inlet wire connection sheet 10 makes inlet wire connection sheet 10 since inertia moves further along
It closes a floodgate completely with outlet connection sheet 80.10 fastener portion of inlet wire connection sheet is contacted with 80 fastener portion of outlet connection sheet pushes outlet connection
The rotation of piece 80 makes inlet wire connection sheet 10 and outlet connection sheet 80 close a floodgate.Outlet connection sheet 80 relies on the drawing of the second tension spring 110
Power and inlet wire connection sheet 10 compress, and Direct Action Type travel switch break contact 180 and the first insulation fixing plate 50 collide, and are disconnected conjunction
The power supply of brake cable circle 70, inlet wire connection sheet 10 are fastened by the first spring tension and outlet connection sheet 80, and realization is reliably connected.
The power supply of magnetictrip uses another bus disconnecting link direct current signal line power supply.Decompression monitor normally-closed contact 170
The electric power loop into magnetictrip iron core 150 is concatenated, the decompression monitor normally-closed contact after local terminal direct current signal route decompression
170 restore conducting；The power circuit of magnetictrip iron core 150 is concatenated into Direct Action Type travel switch moving together contact 160, directly simultaneously
Direct Action Type travel switch moving together contact 160 is connected after dynamic formula travel switch break contact 180 and the collision of the first insulation fixing plate 50,
Show that secondary voltage circuit is in "on" position.Corresponding direct current signal route powers on after another bus bar side disconnecting link combined floodgate, electricity
Magnetic release executes trip action, and Direct Action Type travel switch resets after tripping, and the electric power loop of magnetictrip iron core 150 is disconnected
It opens, the electric power loop of closing coil 70 restores to connect.Tripping execution condition includes that the corresponding bus bar side disconnecting link of local terminal disconnects, that is, is lost
190 decompression of monitor coil is pressed, combined floodgate armature 60 resets under the pulling of the first tension spring 40, decompression monitor normally-closed contact
170 restore conducting；Inlet wire connection sheet 10 and outlet connection sheet 80 are in buckling state, i.e. Direct Action Type travel switch moving together contact
160 conductings；Another direct current signal route electrification, i.e., another bus bar side disconnecting link close a floodgate, and primary system route and main transformer have switched to
Another bus runs corresponding direct current signal route electrification.
The present embodiment is used cooperatively scheme using the devices such as mechanical realization and electromagnetic relay, travel switch, can also be used
Microcontroller and electronic relay (including other controllable devices for being able to achieve Voltage On state with being isolated) and other semiconductors
The design scheme of control device.Because metering secondary has strict demand to pressure drop, in alternative solution main devices electronic type after
Electric appliance directly acts on metering secondary voltage circuit, should not impact to metering secondary voltage, including voltage swing and
Phase.Electronic relay should be able to realize the isolation to voltage in a disconnected situation.
A kind of plant stand electrical energy measurement secondary voltage switching device provided in an embodiment of the present invention is realized to metering secondary voltage
Reliable switching, have the simple feature of wiring, be easy to use maintenance, while solving route and main transformer is in cold standby and maintenance
