MC1a (with reference to Fig. 1) is opened and closed the electromagnet of operation, and this contact element MC1a is used for to work(
The power supply of rate conversion equipment 10 and power-off switch over.
It is more than the structure of the power conversion system 1 comprising charge control system 3.
Fig. 3 is the sequential chart of the action of power conversion system 1 when representing normal.Changing to power
Before device 10 switches on power (for example, the moment t0 of Fig. 3), the normally opened contact unit of catalyst MC2
Part MC2a is open circuit, and normally-closed contact element MC2b is short circuit.Further, since access failure power supply,
Contact element R2a and R3a of interlock circuit ILC opens a way in the lump.In this condition, electric current without flow through
The electromagnet MC1-C of interlock circuit ILC, therefore, the contact element MC1a of catalyst MC1 opens
Road, does not power to power conversion device 10.
Then, in moment t1, if operator carries out pressing the button PB1 of power on/cut-out circuit 21
Operation, then this button PB1 contact element PB1a short circuit.If the short rent of PB1a, electric current flows through
Electromagnet R1-C and R2-C of power on/cut-out circuit 21.Electromagnet R1-C after energising will simultaneously
Connection is connected to the contact element R1a short circuit of the contact element PB1a of button PB1, thus self-sustaining is led to
Electricity condition.Thus, electromagnet R2-C also remains powered on state together with electromagnet R1-C.Additionally,
Flow through the period of this electromagnet R2-C in electric current, electromagnet R2-C is first by the contact of interlock circuit ILC
Part R2a short circuit.
Between terminal 22b1 and 22b2, short because of the normally-closed contact element MC2b of catalyst MC2
Road, therefore, if the contact element R2a short circuit of interlock circuit ILC, electric current flows through electromagnet R3-C
And MC1-C.Electromagnet R3-C after energising will be connected in parallel in terminal 22b1 and 22b2 contact unit
Part R3a short circuit, thus self-sustaining "on" position.Thus, electromagnet MC1-C also with electromagnet R3-C
Remain powered on state together.Additionally, flow through the period of this electromagnet MC1-C, electromagnet in electric current
MC1-C is short-circuit by contact element MC1a.Thus, provide alternating current to power conversion device 10.
If accepting to have alternating current, power conversion device 10 is entered to this alternating current using transducer portion 11
Row rectification, the unidirectional current after rectification is provided to charging circuit 16 thus starting the initial of capacitor 12
Charge.Now, the normally opened contact element MC2a of catalyst MC2 is in open circuit, therefore, via electricity
Resistance device 14 and downtrod electric current flows through capacitor 12.And, both end voltage Vdc of capacitor 12
Risen according to the time being determined by the time constant of resistor 14 and capacitor 12.
Then, if the voltage of capacitor 12 reaches specified level, control unit 19 beginning action.So
Afterwards, control unit 19, through the moment t2 of time set in advance starting from this action, contact is believed
Number export to catalyst MC2.If because of this contact signal, electric current flows through the electromagnet of catalyst MC2,
Then catalyst MC2 is short-circuit by normally opened contact element MC2a, and normally-closed contact element MC2b is opened a way.
That is, control unit 19 is after the charging voltage of capacitor 12 fully rises, normal using catalyst MC2
Opening contact element MC2a will be short-circuit for resistor 14.Thus, capacitor 12 is thoroughly charged.
Additionally, in interlock circuit ILC, being led to come self-sustaining using electromagnet R3-C and contact element R3a
Electricity condition, therefore, even if normally-closed contact element MC2b open circuit, electromagnet MC1-C also maintains energising
State.Therefore, in the midway of the midway of initial charge or common power switching motion, will not cut off
Power supply to power conversion device 10.
In moment t3 afterwards, in order to cut off the electricity supply, pressing operation is carried out to button PB2 by operator,
The then contact element PB2b open circuit of button PB2, electric current is without flow through electromagnet R1-C and R2-C.Become
For non-energized electromagnet R1-C, contact element R1a is opened a way, become non-energized electromagnet R2-C
By the contact element R2a open circuit in interlock circuit ILC.
If the contact element R2a open circuit of interlock circuit ILC, electric current does not flow through electromagnet R3-C
And MC1-C.Contact element R3a is opened a way by the electromagnet R3-C becoming non-energized.Additionally, becoming
Contact element MC1a is opened a way by non-energized electromagnet MC1-C, cuts off to power conversion device 10
Alternating current is provided.If the offer of alternating current is cut off, capacitor 12 discharges, the electricity of capacitor 12
Pressure Vdc declines.If additionally, the voltage of capacitor 12 becomes below assigned voltage (moment t4),
Control unit 19 stops output contact signal.Thus, the normally opened contact element MC2a of catalyst MC2
Open circuit, and normally-closed contact element MC2b short circuit.
Action when being more than normal.
Herein, in the state of power conversion device 10 carries out common power switching motion, catalyst
The contact of the normally-closed contact element MC2a of MC2 is welded and is become short trouble.Fig. 4 is to represent
The sequential chart of the action of power conversion system 1 now.Carry out common work(in power conversion device 10
In the state of rate switching motion, normally opened contact element MC2a becomes short-circuit condition.Thus, for example,
Even if in moment t10, there is welding, also can maintain in this moment in the contact of normally opened contact element MC2a
Common power switching motion.
Afterwards, in moment t13, for the power supply of rupturing duty conversion equipment 10, by operator to pressing
Button PB2 carries out pressing operation.If pressing operation is carried out to button PB2, with normal when identical,
By the contact element R2a open circuit of interlock circuit ILC, electromagnet R3-C and MC1-C becomes non-energized,
Contact element R3a and MC1a opens a way.Therefore, with normal when identical, cut off to power converting means
Put 10 offer alternating currents, the voltage Vdc of capacitor 12 declines.
If the voltage Vdc of capacitor 12 declines and become below assigned voltage, control unit 19 stops
Output contact signal.However, the contact of the normally opened contact element MC2a of catalyst MC2 does not occur
Welding, therefore, even if the contact signal providing from control unit 19 stops also becoming open circuit, can tie up
Hold short-circuit condition.Additionally, the normally-closed contact element MC2b of catalyst MC2 and normally opened contact element
MC2a carries out mechanicalness linkage, therefore, even if the contact signal providing from control unit 19 stops also
Maintain open-circuit condition.Therefore, maintain open circuit shape between terminal 22b1 and 22b2 of interlock circuit ILC
State.
Afterwards, in moment t21, in order to make power conversion device 10 rise again it is assumed that by operator
Pressing operation is carried out to button PB1.By this operation, the contact element PB1a of button PB1 is short-circuit,
Electric current flows through electromagnet R1-C and R2-C, contact element R2a short circuit in interlock circuit ILC.
However, due to the short trouble of normally opened contact element MC2a, between terminal 22b1 and 22b2
Become open circuit, and contact element R3a becomes open circuit, therefore, even if contact element R2a is short-circuit,
Electromagnet R3-C and the non-power status of electromagnet MC1-C can be maintained.Therefore, maintain contact element
The open circuit set of MC1a, maintains the cut-out of the alternating current of power conversion device 10.Do not start to power
Conversion equipment 10 is powered, and therefore, the initial charge of capacitor 12 does not start, the voltage of capacitor 12
Vdc does not rise.
Afterwards, in moment t23, if operator carries out pressing operation, button PB2 to button PB2
Contact element PB2b open circuit, interlock circuit ILC contact element R2a open circuit.Electromagnet R3-C
Just had become as non-power status with electromagnet MC1-C before contact element R2a will open a way, because
This, after contact element R2a open circuit, remain on and can maintain non-power status.Therefore, maintain contact
The open-circuit condition of element MC1a.
As described above, in the power conversion system 1 comprising charge control system 3 of present embodiment,
It is short-circuited fault and normally-closed contact element MC2b in the normally opened contact element MC2a of catalyst MC2
In the state of maintaining open-circuit condition, stop and start to power to capacitor 12.This passes through normally-closed contact element
Input and output terminal 18b1 and 18b2 that MC2b exports I/F18 with outside input is connected and fetches realization.
In the state of normally opened contact element MC2a is short-circuited fault, will not start to battery charge controller 5
Power supply, accordingly, it is capable to prevent larger surge current from flowing through capacitor 12 in advance.Thus, because of catalyst
The fault of MC2 and make capacitor 12, the diode in transducer portion 11 also break down this
The situation of failure propagation can be prevented, can be by the failure restraint of power conversion device 10 to irreducible minimum.
Therefore, only pass through exchange catalyst MC2 and just can repair power conversion device 10.Additionally, turning in power
Change in system 1, under the idle state of control unit 19, also can reliably prevent compared with billow in advance
Gush electric current and flow through capacitor 12.Additionally, in power conversion system 1, power to capacitor 12
Under state, even if normally-closed contact element MC2b opening and closing, also can maintain the power supply to capacitor 12, because
This, the power supply that will not interrupt to capacitor 12 when way in charging.
