Embodiment
The embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that
Embodiment described herein is merely to illustrate and explain the present invention, and is not limited to this hair
It is bright.
The configuration logic module of comprehensive protector provided by the present invention includes:Service condition judges mould
Block, it is used for:Judge whether system possesses unlocking condition;Alarm is driven when system does not possess unlocking condition
Device is alarmed.
Service condition judge module can be configured to detect the system deposit one in the following or
Judge that the system does not possess the unlocking condition during more persons:The non-energy storage of system switching contained spring, open circuit
Device is not at working position.And detecting that the system deposits one or more not confirmed in the following
Judge that the system does not possess the unlocking condition during failure:System is in excessively stream startup, system was in
Flowing is made, produces zero-sequence current in generation residual voltage, loop in loop.Exist once in this expression system
Through starting in excessively stream or once once being produced in residual voltage or loop in excessively stream action or loop
The failure but non-site inspection for once producing zero-sequence current confirm failure cause.Wherein, inside system switching
In the case of spring unstored energy, system switching will be caused to close, system can not normally start;Open circuit
Device is under the state of inoperative position, and system also can not normally start.
Fig. 1 shows that the logic of the service condition judge module of comprehensive protector provided by the present invention is shown
It is intended to.As shown in figure 1, system is in, excessively stream starts, system is in excessively stream action, loop and produces zero
Zero-sequence current these four signals are produced in sequence voltage, loop to enter or door, enter back into can hand-reset from
Retainer, the signal come out from self-insurance holder, then breaker working position, system switching with " negating "
The non-energy storage of contained spring enters or door together, judges whether system has according to the signal come out from the OR gate
Standby unlocking condition, the non-energy storage of system switching contained spring, breaker are not at working position, system was in
Stream starts, system is in excessively stream action, loop to produce in residual voltage, loop and produced in zero-sequence current
Any one or more persons occur the signal value can be caused to be not zero, in the case where the signal value is not zero
Judgement system does not possess unlocking condition, judges that system possesses unlocking condition when the signal is low level.
With further reference to Fig. 1, in the case where system does not possess unlocking condition, the level signal that is not zero
LED1 lamps can be driven bright, and then remind staff further to be repaired.So as to ensure that system is transported
Capable reliability.
In addition, generation zero sequence is electric in system is in excessively stream action, loop and produces residual voltage, loop
Flow can also increase in the circuit of these three signals LED (LED2, LED4 as shown in Figure 1,
LED6) lamp prompts personnel systems not possess the producing cause of unlocking condition, to facilitate work people
Member carries out trouble shooting or maintenance.
Belong to system be in excessively stream starts, system be in excessively stream action, residual voltage is produced in loop, time
In road produce zero-sequence current failure be eliminated after, staff can carry out hand-reset so that from
The signal that " self-insurance holder " comes out is changed into zero-signal.
Further, the configuration logic module of comprehensive protector provided by the present invention can also include:
Locking prepared auto restart module, in the system operation break down in the case of locking prepared auto restart work(
Energy.Preferably, the duration of overcurrent in the loop is could be arranged to more than 0.6 second and/or loop
In the case that the duration of middle zero-sequence current was more than 0.5 second, described in the locking prepared auto restart module locking
Backup power automatic switching function.Fig. 2 is the logic of the locking prepared auto restart module of comprehensive protector provided by the present invention
Schematic diagram.As shown in Fig. 2 overcurrent signal and zero sequence current signal enter or door, can hand entering
Dynamic " the self-insurance holder " resetted, when the signal come out from " self-insurance holder " is non-zero signal, locking institute
State backup power automatic switching function.After the Failure elimination of " overcurrent " and " zero-sequence current ", efforts people
Member can carry out hand-reset so that the signal come out from " self-insurance holder " is changed into zero-signal, and then unlocks
Backup power automatic switching function.Here, a LED can be set (as shown in Figure 2 in locking prepared auto restart module
LED3), in the case where backup power automatic switching function is blocked, the LED is bright to prompt staff.
In the present invention, BOO4 and BOO5 in Fig. 2 and Fig. 3 refer to that corresponding comprehensive protector is held
Row mechanism, i.e. output switch parameter.
In addition, the configuration logic module of comprehensive protector provided by the present invention can also include:Failure
Recording module, for recording the fault-signal of the system in the case of system failure.Institute
State failure wave-recording module and be arranged to startup separator recording function during one or more of following generation:Zero

Less than 95% voltage signal.The failure wave-recording module record particular content include running current, voltage,
All kinds of malfunctions, running status etc..
Fig. 3 is the logical schematic of the failure wave-recording module of comprehensive protector provided by the present invention.Such as
Shown in Fig. 3, zero sequence current signal, residual voltage signal, the divide-shut brake signal, low of breaker working position
In less than 95% voltage signal of rated voltage, failure wave-recording mould can be triggered after a pulse delay
Block carries out fault-signal recording.Here, the divide-shut brake signal of breaker working position can be divided into breaker conjunction
Position signal, breaker working position signal, breaker divide position signal.Less than less than the 95% of rated voltage
Voltage signal refers to that the voltage signal in loop is less than the 95% of rated voltage, can set a LED
(LED7 as shown in Figure 3), voltage signal in the loop less than rated voltage 95% in the case of,
The LED etc. is bright to prompt staff.In addition, staff can select required event as needed
Hinder signal and carry out recording, for example, only perform the recording of zero sequence current signal etc., do not make specific limitation.
Further, in the present invention can be by logic chart come configuration logic module described in specification.
Lack logic chart and carry out specification configuration logic module, just occur that programming personnel's configuration is random and ask
Topic, i.e., different programming personnels, can be according to itself hobbies or by own level in order to realize identical function
The factors such as influence use different configuration methods, cause comprehensive protector internal configuration inconsistent, do not advise
Model, or even there is gross error, cause protection device malfunction or tripping, influence the reliability of system operation.
In addition, the appearance of logic chart, which also allows for non-programmed technical staff, understands comprehensive protector internal configuration
Logic, while the debugging foundation of comprehensive protector logic function is also provided for field adjustable personnel,
Ensure the correct action message of protection device, improve power supply reliability.
