The mimic-disconnecting has the advantages that the equipment principle is simplified, the equipment device is reduced and the equipment weight is lightened.
Description
Technical field
The utility model belongs to relay protection field in the power engineering, relates to a kind of technology of true isolating switch being simulated realization.
Background technology
Have producer's manufactured simulated isolating switch on the market, generally taking single-chip microcomputer or DSP is the microcomputer type design of chip, can realize that function is closed in the jumping of three-phase breaker, and a mimic-disconnecting switch market price is about about 50,000 yuan.Yet producer's manufactured simulated isolating switch function is complicated, and volume is big, and Heavy Weight is fit to breadboard precision measurement demand, and it is very unnecessary to use for our daily work on the spot, and cost is expensive.
Adopt the microcomputer type design to prior art, the realization three-phase breaker is jumped and is closed, and routine work does not need the problem of this function, so the single-phase mimic-disconnecting switch of simplicity of design.
Summary of the invention
To the prior art complex structure, volume is big, the shortcoming of Heavy Weight, and the utility model provides a kind of mimic-disconnecting switch, thereby reaches the simplified apparatus principle, reduces equipment volume, alleviates the purpose of weight of equipment.
The technical scheme of the utility model is achieved in that
Practical mimic-disconnecting switch is by forming with the lower part:
Positive negative control bus ± KM connects the 220V direct supply;
Switch knob HA links to each other closing relay HQ and its parallel resistance R with+KM
1Be connected to switch knob HA rear side, again with the normally closed contact DL of auxiliary contact relay
2Series connection meets negative control bus-KM;
Trip button TA links to each other with positive control bus+KM, tripping relay TQ and its parallel resistance R
2Be connected to trip button TA rear side, again with the normal opened contact DL of auxiliary contact relay
1Series connection meets negative control bus-KM;
The normal opened contact DL of auxiliary contact relay
1With tripping relay normally closed contact TQ
2The series connection back is parallelly connected with closing relay normal opened contact HQ1, a side joint positive control bus+KM, and a side joint auxiliary contact relay DL is to negative control bus-KM;
The normally closed contact DL of auxiliary contact relay
2And green light LD is connected on ± the positive negative control bus of KM between;
The normal opened contact DL of auxiliary contact relay
1And red light HD is connected on ± the positive negative control bus of KM between.
The utility model adopts and utilizes 3 auxiliary reclays, realizes the isolating switch function through the incompatible simulation of rational logical groups.
Principle is succinct, and reliability is high: use 3 relays and other simple electronic original parts to make, relay is controlled the realization function each other, and principle is simple and clear.
Reliability is high: because what take is not the implementation of semiconductor equipments such as microcomputer type single-chip microcomputer or DSP, but the stable and reliable operation relay, can improve the maintenance level of equipment greatly and to the adaptability of temperature humidity.
Volume is little: 3 relays can be installed in about 15 * 15cm
2Printed circuit board (PCB) on, it is very little to have determined that casing can be done.Actual volume is less than 1/3rd of general commercially available mimic-disconnecting switch volume.
In light weight: because structure and implementation are simple, the whole instrument volume is very light, has only about 200 grams the mimic-disconnecting switch volume that general commercially available 5kg is above.
Single-phase circuit breaker breaker tripping and closing function: realize simple single-phase circuit breaker breaker tripping and closing function.
The saving funds: manufactured simulated isolating switch cost is in 500 yuan, and general ten thousand yuan commercially available equipment has greatly embodied economy.
Description of drawings
Fig. 1 is the utility model analog breaker circuit connection layout.
Below in conjunction with accompanying drawing the content of the utility model is done further explain.
Embodiment
With reference to shown in Figure 1, use 3 relays and contact thereof to realize the circuit logic of mimic-disconnecting switch function, from figure, can it is evident that the terseness of design concept.
Use practical mimic-disconnecting switch to carry out the protective relaying device test; The breaker tripping and closing outlet of handle assembly is connected to practical mimic-disconnecting switch breaker tripping and closing porch; Device DC220V power port place connects the 220V direct supply, turns on the power switch, and just can realize simulating the simulation of single-phase circuit breaker; Device provides 2 groups of extra output contacts simultaneously, can connect into relay-protection tester return contact test both opens device breaker tripping and closing time of return.
When protective relaying device provided switching signal, closing relay HQ coil was charged, and closing relay often leaves and meets HQ
1Point is closed, connects auxiliary contact relay DL coil, the normal opened contact DL of auxiliary contact relay
1Closure is because tripping relay normally closed contact TQ
2Be failure to actuate, auxiliary contact relay DL coil keeps, and red light is bright, and instrument forms "on" position;
Give action when protective relaying device, when perhaps directly providing trip signal, instrument tripping relay TQ coil is charged, tripping relay normally closed contact TQ
2Open, auxiliary contact relay DL resets, the normally closed contact DL of auxiliary contact relay
2Closure, green light is bright, and instrument is realized tripped condition.
One of them relay is realized closing coil outlet function, and a relay is realized breaking coil outlet function, and another relay is selected as the logic of two relays in auxiliary contact control front:
Provide switching signal when pressing switch knob HA or device, closing relay HQ coil is charged, and closing relay often leaves and meets HQ
1Point is closed, connects auxiliary contact relay DL coil, the normal opened contact DL of auxiliary contact relay
1Closure is because tripping relay normally closed contact TQ
2Be failure to actuate, auxiliary contact relay DL coil keeps, and red light is bright, and instrument forms "on" position;
Provide trip signal until pressing trip button TA or device, tripping relay TQ coil is charged, tripping relay normally closed contact TQ
2Open, auxiliary contact relay DL resets, the normally closed contact DL of auxiliary contact relay
2Closure, green light is bright, and instrument is realized tripped condition.
As above, adopt 3 auxiliary reclay simulations can realize the following basic function of microcomputer type mimic-disconnecting switch:
(1) can show current circuit breaker position and keep watch on jump, closing loop through traffic lights;
(2) can realize breaker protection breaker tripping and closing function;
(3) can realize breaker remote breaker tripping and closing function;
(4) can realize isolating switch divide-shut brake function on the spot.
