Module shutting-brake control lines in parallel is constituted, and string is equipped with the first auxiliary switch and corresponds to disconnected on each breaker module shutting-brake control circuit
The shutting-brake control coil of road device module closes a floodgate for controlling corresponding breaker module.It therefore, can be real by way of in parallel
Now the shutting-brake control coil of all breaker modules achievees the purpose that while closing a floodgate simultaneously by electricity.Due to being closed in control breaker
When lock, the first auxiliary switch action for controlling each breaker module shutting-brake control circuit simultaneously is needed, it therefore, can be by all conjunctions

Road device module sub-control gate line road parallel connection is constituted, and each breaker module sub-control gate line road string is equipped with the second auxiliary switch and right
The sub-control gate line circle for answering breaker module, for controlling corresponding breaker module separating brake.Therefore, the energy by way of in parallel
Enough realize that the sub-control gate line circle of all breaker modules simultaneously by electricity, achievees the purpose that while separating brake.Due in control open circuit
When device separating brake, the second auxiliary switch action for controlling each breaker module sub-control gate line road simultaneously is needed, it therefore, can be by institute
There is the second auxiliary switch in separating brake branch as an auxiliary switch, in this case specially normally closed auxiliary switch S0.1 leads to
Cross control the normally closed auxiliary switch S0.1 can control simultaneously all breaker modules sub-control gate line circle action.With it is upper
Normally closed auxiliary switch S0.1 is stated similarly, by the sub-control gate line circle of all breaker modules as a control coil, for control
Coil YT1 processed, as shown in figure 3, this makes it possible to control all breaker module separating brakes simultaneously.
So, it when controlling high voltage circuit breaker closing, controls normally closed auxiliary switch S0 and is closed, shutting-brake control coil YC1 is obtained
Electricity, each breaker module close a floodgate, i.e. high voltage circuit breaker closing；When controlling high-voltage circuitbreaker separating brake, normally closed auxiliary switch is controlled
S0.1 is closed, and sub-control gate line circle YT1 obtains electric, each breaker module separating brake, i.e. high-voltage circuitbreaker separating brake.Certainly, normal conditions
Under, in normally closed auxiliary switch S0 and normally closed auxiliary switch S0.1, when being closed there are one switch, another switch must be in disconnected
Open state.
Further, in order to avoid high-voltage circuitbreaker, in separating brake, combined floodgate branch misleads, and division brake control device also wraps

There are two breaker modules, then anti-jump control module to be made of two anti-jump control circuit parallel connections for each combined floodgate branch road.It is each anti-
It jumps string in control circuit and is equipped with third auxiliary switch.When the first auxiliary switch is closed, high-voltage circuitbreaker is in "on" position, this
When third auxiliary switch to be off state, on the contrary, when the first auxiliary switch turns off, high-voltage circuitbreaker is in separating brake shape
State, third auxiliary switch will be in closed state at this time, and therefore, the on off state of the first auxiliary switch will be with third auxiliary switch
On off state it is opposite always.Due to third auxiliary switch and the first auxiliary switch close association, then, third auxiliary switch with
First auxiliary switch is the same, is also indicated using auxiliary switch S0, but unlike, since the first auxiliary switch is normally closed
Auxiliary switch S0, then, third auxiliary switch is just normally opened auxiliary switch S0.Further, anti-jump control module also with it is anti-jump
The second contact shunt of relay KF11 connects, which is normally opened contact.Therefore, it is opened by the auxiliary of A1 columns and A2 columns
The form of coila parallel connection starts anti-trip relay, to achieve the purpose that disconnect combined floodgate branch after anti-trip relay starts.
Therefore, when high-voltage circuitbreaker belongs to gate-dividing state, the first auxiliary switch disconnects at this time, i.e., normally closed auxiliary switch S0
It disconnects, then third auxiliary switch, i.e., normally opened auxiliary switch S0 is closed, and the control coil of anti-trip relay obtains electric, anti-trip relay
Normally-closed contact disconnect, i.e., combined floodgate branch disconnect, it is ensured that combined floodgate branch cannot be connected, and avoid misleading for combined floodgate branch, and
And the normally opened contact of anti-trip relay is closed, and makes anti-jump branch constant conduction, persistently prevents combined floodgate branch from malfunctioning.
As shown in figure 3, for any one breaker module sub-control gate line road, the second auxiliary switch, i.e., normally closed auxiliary
Switch S0.1 is connected in parallel with the 4th auxiliary switch, the on off state of the 4th auxiliary switch and the switch shape of the first auxiliary switch
State always on the contrary, with it is above-mentioned similarly, the 4th auxiliary switch and the first auxiliary switch close association, then, the 4th auxiliary switch
It is indicated using auxiliary switch S0, but unlike, since the first auxiliary switch is normally closed auxiliary switch S0, then, the
Four auxiliary switches are just normally opened auxiliary switch S0.In this case, when controlling high voltage circuit breaker closing, normally closed auxiliary switch S0 is closed
It closes, normally opened auxiliary switch S0 is disconnected, and can ensure that separating brake branch is off-state.
