Embodiment
As shown in Figs. 1-5, intelligent subscriber boundary switch controllers use stainless steel 304 shell, by intelligent switch controller,
Knob, opening button, switch knob, start battery, alternating-current switch, cell switch, charging socket, Inverter, battery,
The critical pieces such as GSM antenna form, and the intelligent switch controller also there is remote control, remote measurement and remote signaling function, the intelligence to open
Closing controller has time adjustment function, by dispatching communication pair when, SMS pair when or during test software pair.Intelligent subscriber points
Boundary's switch controller is communicated by GPRS modes with monitoring center, and the various work informations of operation are reported with Chinese short message mode.
Short message is arranged to send out or do not send out, and makes test more convenient.Intelligent subscriber boundary switch controllers coordinate with prepayment meter, energy
Enough realize pre-payment control function.Ground protection can select band direction or without direction, and short message can set hair or not send out, and make
Test more convenient, on-off model can be negated with software.
The control loop schematic diagram shown in electric power loop schematic diagram and analog quantity schematic diagram, Fig. 7, Fig. 8 according to Fig. 6
Shown open entry loop schematic diagram, the defencive function and operation principle of intelligent subscriber boundary switch controllers are as follows：
The failure of 10KV feeder lines or equipment can be handled, the failure of 10KV feeder lines or equipment mainly has phase fault
With single-phase earthing two types, both failures are respectively processed：
1st, the processing of phase fault
For the phase fault in user circle, intelligent switch controller is by detecting the collection inside demarcation switch
A C phase currents and definite value relatively carry out the generation of failure judgement, when more than definite value, tripping Fault Isolation to fall immediately, do not influence non-
The power supply of fault zone.Even if due to the selective problems of definite value, some failures cause substation's outlet switch and also trip,
But after substation overlaps, trouble point has been isolated, and non-faulting region can restore electricity quickly.If two sections of specified time overcurrents are protected
Protect (quick-break, overcurrent), each section of electric current and time definite value can adjust independently, set respectively and adjust control word and control this two sections protections
Throwing is moved back, and overload can select to trip or alert.One section of accelerating sections current protection is specially set, is put into 3 seconds after reclosing, and
It is not that selection accelerates quick-break, overcurrent.It can be thrown and moved back by control word, the electric current of accelerating sections and time can independently adjust.
2nd, the processing of singlephase earth fault
Singlephase earth fault, zero-sequence current during generation singlephase earth fault in user circle is much smaller than due to zero-sequence current,
Therefore, by setting appropriate definite value, you can make accurate judgement, can select to trip or alert.
When motor three-phase current has larger asymmetry, there is larger negative-sequence current, and negative-sequence current will in the rotor
The electric current of 2 times of power frequencies is produced, rotor is added fever and greatly increases, jeopardize the safe operation of motor.Device sets two sections to determine
Time limit negative phase-sequence overcurrent protection, respectively disconnected phase anti-phase to motor, turn-to-turn short circuit and more serious asymmetrical voltage etc. are transported extremely
Row operating mode provides protection, wherein II section of sensitive unbalanced current protection of conduct of negative phase-sequence overcurrent, is selected by control word FGLFSX
Using specified time or inverse time lag.Device has maximum No. four reclosings, and each throwing, which is moved back, individually to be controlled, each delay energy
It is enough independently to adjust.
Possess remote control, remote measurement, remote signaling function, distant control function has：Trip operation is remotely controlled, is remotely controlled closing operation.Hand-held remote control
Device trip operation on the spot, on the spot closing operation；Remote measurement amount mainly has：IA IC I0, precision reach 0.5 grade；Remote signalling amount mainly has：
9 tunnel remote signalling are opened into the displacement remote signalling of, device and accident remote signalling, and make sequence of events recording, and remote signalling resolution ratio is less than 2ms.
Possess item record and preserve function, 32 sequence of events recording (SOE records) can be stored, and 16 protections are moved
Note down, power down does not disappear, and facilitates recollecting and analyzing for accident.
Possess time adjustment function, by during dispatching communication pair either mobile phone by during short message pair or use test software pair
When.It can realize automatic transmission item SMS function, monitor the change of presence states in real time, once change immediately to specified
Phone number (can be multiple cell-phone numbers) send event report.It can realize remote meter-reading function, reserve 485 communications
Mouthful, 1-8 block electric energy meters, the data of device automatic collection electric energy meter can be connect, and upload is forwarded, realize remote meter reading.
The utility model is not limited to the above embodiment, and every various changes to the utility model do not depart from this reality
With new spirit and scope, if these modification and variations belong to the claims and equivalents of the utility model scope it
Interior, then the utility model is also implied that comprising these modification and variations.
