Description
Technical field
The present invention relates to a kind of multi-way intelligence and leak guarantor's uninterrupted power test device online.
Background technology
The rural power grids RCD (being called for short leakage to protect) of National Energy Board installs fortune
Pointing out in professional etiquette journey, rural low voltage network classification installing leakage guarantor is to ensure that low voltage electric network is transported safely
Go, reduce or prevent one of effective measures of person electric shock casualty accident, the public change in rural area
The total guarantor in depressor platform district should be installed by power supply enterprise, is arranged in the bus of transformer platform area or each
Bar is maked somebody a mere figurehead on lead-out wire, and leakage is protected and preferably used electromechanical three-phase and four-line protector and meet rule
Fixed combined protector.Leakage is protected and is required monthly test action characteristic, thunder in operational management
Rainy season tests weekly once.
Protect due to leakage and need routine test, trial jump in operational management, can cause in operation
Low-voltage customer dead electricity, reduces power supply reliability and adds the Frequent trip that client thinks.
At present, rural comprehensive transformator is divided into multichannel outlet substantially, essentially 3~5 tunnel outlets,
Every road outlet is fitted with Lou protecting, and tester every road leakage guarantor is necessary for installing a set of, wiring change
Many, especially for distribution box, clearance spaces is little, often overlaps and all fills tester and just have any problem.
Summary of the invention
It is an object of the invention to provide a kind of rational in infrastructure, wiring simple, it is reliable to improve power supply
Rate and leakage are protected integrity and can leak guarantor's uninterrupted power test online by the multi-way intelligence tested respectively of multichannel
Device.
The technical solution of the present invention is:
A kind of multi-way intelligence leaks guarantor's uninterrupted power test device online, it is characterized in that: include that intelligence exists
The controller that do not has a power failure is protected in line leakage, and intelligent online leakage is protected the controller that do not has a power failure and is connected to organize test loop more
With corresponding many group relaies;The leakage of described intelligent online is protected the controller that do not has a power failure and is included being connected on contact
The first current sensor between device contact is protected in device and leakage, and an end of the second current sensor is connected to
Between catalyst and the first current sensor, the other end of the second current sensor and the first relay
The contact of device connects, the contact phase-connecting wire L1 of the first relay;One leakage currents resistance one end
Being connected with zero line, the contact of the other end and the second relay connects, and the contact of the second relay connects
Phase line on rear side of test loop transformer;First, second relay is in parallel, first, second relay
One terminal connecting zero line of device, the other end is connected with controller, controller phase-connecting wire L1, controller
It is provided with remote-control communication interface.
Present configuration is reasonable, and wiring is simple, can be to leakage in the case of not to client's power-off
Guarantor carries out testing, trial jump, improves power supply reliability and integrity is protected in leakage;And can multichannel survey respectively
Examination.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 protects, for intelligent online leakage, the controller that do not has a power failure in dotted line frame.
Detailed description of the invention
A kind of multi-way intelligence leaks guarantor's uninterrupted power test device online, protects including intelligent online leakage and does not stops
Electric controller, intelligent online leakage is protected the controller that do not has a power failure and is connected to organize test loop with the most more
Group relay (often 2 relays of group);The leakage of described intelligent online is protected the controller that do not has a power failure and is included
It is connected on catalyst JCQ and leaks the first current sensor LJ1 protected between device LBQ contact, second
One end of current sensor LJ2 is connected between catalyst JCQ and the first current sensor LJ1,
The other end of the second current sensor LJ2 and the contact of the first relay k1 connect, and first continues
The contact phase-connecting wire L1 of electrical equipment k1;One leakage currents resistance R one end is connected with zero line N, separately
One end is connected with the contact of the second relay K 2, and the contact of the second relay K 2 connects test loop
Phase line on rear side of transformer;First, second relay is in parallel, one end of first, second relay
Connecting to neutral line N, other end phase-connecting wire L1.
The testing sequence of controller of not having a power failure is protected in intelligent online leakage:
1, K1 closes, and LJ1 electric current reduces, and LJ2 electric current increases, and confirms that K1 closes;
2, K2 closes, and leaks guarantor's action, and LJ1 is 0, and LJ2 electric current increases, and confirms leakage guarantor's action;
3, K2 disconnects, and LJ2 reduces, and LJ1 increases, and confirms that leakage is protected and closes;
4, K1 disconnects, and test terminates.
Test automatically can be timed, connect the remote-controlled distant place of order circuit and test and return knot
Really;For prevent phase place wrong short circuit, intelligent online leakage protect do not have a power failure controller with leakage protect power supply with
Phase place, i.e. connects control power supply from leakage is protected;Working power is defaulted as AC220V, and scene such as connects
When tentaculum is AC380V, switchable power supply pattern, the data of current sensor send control to
Device carries out logical relation judgement;Protect wiring with leakage and only need several (Φ 1~Φ 4);Φ 5 connects test
Phase line (best and L1 homophase) on rear side of the transformer of loop.
Multi-channel test order:
Elder generation's Kn-1 adhesive, then Kn-2 adhesive again during test current loop;Exit test current
Elder generation Kn-2 dead electricity during loop, then Kn-1 dead electricity again, disconnect with current loop.Kn-2 is with double
Normally closed be to ensure that reliable.
