Description

Multi-way intelligence leaks online protects uninterrupted power test device
Technical field
The present invention relates to a kind of multi-way intelligence and leak online guarantor's uninterrupted power test device.
Background technology
Rural power grids RCD (be called for short to leak and protect) the installation and operation code of National Energy Board; rural low voltage network classification installing is leaked guarantor and is ensured low voltage electric network safe operation, reduces or prevent one of effective measures of personal electric shock casualty accident; the Zong Baoyingyou power supply enterprise in common transformer platform district, rural area installs; be arranged in the bus of transformer platform area or on each built on stilts extension line, leak and protect the combined protector that should adopt electromechanical three-phase and four-line protector and conform with the regulations.Leak and protect a monthly test action characteristic of requirement in operational management, thunderstorm season is tested weekly once.
Need routine test, trial jump owing to leaking to protect in operational management, in operating process, can cause low-voltage customer dead electricity, reduced power supply reliability and increased the Frequent trip that client thinks.
At present, rural comprehensive change is divided into multichannel outlet substantially, is 3 ~ 5 tunnel outlets substantially, the outlet of every road is all provided with Lou and protects, and the every road leakage of tester guarantor is a set of with regard to installing, and wiring change is many, especially little for panel box clearance spaces, every cover all fills tester and just has any problem.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, wiring is simple, improve power supply reliability and leak and protect integrality, and the multi-way intelligence of can multichannel testing respectively leaks online and protects uninterrupted power test device.
Technical solution of the present invention is:
A kind of multi-way intelligence leaks online protects uninterrupted power test device, it is characterized in that: comprising that intelligent online is leaked protects the controller that do not have a power failure, and intelligent online is leaked and protected the controller that do not have a power failure and be connected to many group test loops and corresponding many group relaies; Described intelligent online leakage is protected the controller that do not have a power failure and is comprised the first current sensor being connected between contactor and leakage guarantor device contact, one end of the second current sensor is connected between contactor and the first current sensor, the other end of the second current sensor is connected with the contact of the first relay, the contact phase-connecting wire L1 of the first relay; A leakage current resistance one end is connected with zero line, and the other end is connected with the contact of the second relay, and the contact of the second relay connects test loop mutual inductor rear side phase line; First, second relay parallel connection, a terminal connecting zero line of first, second relay, the other end is connected with controller, controller phase-connecting wire L1, controller is provided with remote-control communication interface.
The present invention is rational in infrastructure, and wiring is simple, can be not to client's power-off in the situation that to leak protect test, trial jump, improve power supply reliability and leak and protect integrality; And can multichannel test respectively.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of one embodiment of the invention.
In Fig. 2, in dotted line frame, leak and protect the controller that do not have a power failure for intelligent online.
Embodiment
A kind of multi-way intelligence leaks online protects uninterrupted power test device, comprises that intelligent online is leaked to protect the controller that do not have a power failure, and intelligent online is leaked and protected the controller that do not have a power failure and be connected to many group test loops and corresponding many group relaies (every group of 2 relays); Described intelligent online leakage is protected the controller that do not have a power failure and is comprised the first current sensor LJ1 being connected between contactor JCQ and leakage guarantor device LBQ contact, an end of the second current sensor LJ2 is connected between contactor JCQ and the first current sensor LJ1, the other end of the second current sensor LJ2 LJ2 is connected with the contact of the first relay k1, the contact phase-connecting wire L1 of the first relay k1; A leakage current resistance R one end is connected with zero line N, and the other end is connected with the contact of the second relay K 2, and the contact of the second relay K 2 connects test loop mutual inductor rear side phase line; First, second relay parallel connection, a terminal connecting zero line N of first, second relay, other end phase-connecting wire L1.
Intelligent online is leaked the testing sequence of protecting the controller that do not have a power failure:
1, K1 closes, and LJ1 electric current reduces, and LJ3 electric current increases, and confirms that K1 closes;
2, K2 closes, and leaks and protects action, and LJ1 is that 0, LJ2 electric current increases, and confirmation is leaked and protected action;
3, K2 disconnects, and LJ2 reduces, and LJ1 increases, and confirms to leak to protect and closes;
4, K1 disconnects, and test finishes.
Can carry out timing automatic test, connect the remote-controlled distant place of order circuit and test and return results; For preventing the short circuit of phase place wrong, intelligent online is leaked and is protected do not have a power failure controller and leakage guarantor power supply same-phase, connects control power supply from leaking to protect; Working power is defaulted as AC220V, when scene is AC380V as contactor, and switchable power supply pattern, the data of current sensor send controller to and carry out logical relation judgement; Protect wiring with leakage and only need several (Φ 1 ~ Φ 4); Φ 5 connects test loop mutual inductor rear side phase line (being better than L1 homophase most).
Multi-channel test order:
Test is first Kn-1 adhesive in the time of front loop, then Kn-2 adhesive again; Exit test first Kn-2 dead electricity in the time of front loop, then Kn-1 dead electricity again, and disconnects when front loop.Kn-2 with two normally closed be guarantee reliable.
