Abstract
The utility model relates to a low voltage distribution operation control, which is characterized in that: three two-color signal lamps are arranged in the same row in sequence, which respectively display the on-off status of a two incoming breaker and a bus interconnecting breaker; the two incoming breaker and the bus interconnecting breaker are electrically interlocked to ensure that the two power supplies do not parallel run. The utility model has the advantages that when the device is in operation, people can know the operation mode of distribution at one place by the indication of the signal lamps and the on-site operation is very convenient.
Description
Technical field
The utility model relates to a kind of distribution operation controller, particularly a kind of Low Voltage Distribution Operation Controller.
Background technology
By in the two-way power supply power supply plan, when normally moving, the two-way power supply divides open shop at present, when power failure of one road power supply or maintenance, and the bus-tie circuit breaker that can close, by the power supply of one road power supply, thus the flexibility of assurance power supply.The branch that closes of the lead-in circuit breaker of two-way power supply and bus-tie circuit breaker is operated, and is respectively to control on every cabinet.The execute-in-place inconvenience because of the installation of low-voltage distribution cabinet, generally is that incoming line cabinet is installed at two, and the centre is a bus contact cabinet, no matter be the power supply of two-way power supply, still one road power supply power supply all must be gone to the sub-front of every cabinet and go operation.And equipment also is inconvenient to know the operational mode of distribution when operation.
Summary of the invention
The purpose of this utility model provides Low Voltage Distribution Operation Controller, and as long as it by the signal lamp indication, just can know the operational mode of distribution a local operation.
The utility model is achieved like this, it comprises three double-colored signal lamps, rotary knob, switch knob, it is characterized in that, at a local operation bus-tie circuit breaker and two-way lead-in circuit breaker, three double-colored signal lamps are arranged in a row in order, what show one road lead-in circuit breaker, bus-tie circuit breaker, two road lead-in circuit breakers respectively closes the branch shape, rotary knob is contained in below the signal lamp of bus-tie circuit breaker, selection as contact cabinet control power supply, three switch knobs are arranged in order, control the combined floodgate of three circuit breakers respectively.
The utility model has the advantages that: during equipment operation, as long as people by the signal lamp indication, just know the operational mode of distribution a local operation, and execute-in-place is convenient.
Description of drawings
Fig. 1 is a functional-block diagram of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, bus contact cabinet 5 of the present utility model is controlled one road electric power incoming line cabinet 4 and two road electric power incoming line cabinets 6 respectively, reciprocal interlocking between the switching signal of lead-in circuit breaker, the status signal of circuit breaker and bus and the incoming line cabinet circuit breaker is by secondary control cable transmission signals.
As shown in Figure 2,1QF represents one road electric power incoming line circuit breaker, and QF represents to get in touch with cabinet breaker, and 2QF represents two road electric power incoming line circuit breakers, and X represents the breaker closing coil.Three double-colored signal lamps 1 are arranged in a row in order, show the branch state that closes of two-way lead-in circuit breaker and bus-tie circuit breaker respectively.Rotary knob 2 is contained in below the signal lamp of bus-tie circuit breaker, under the situation of one road power supply power supply, selects the control power supply of contact cabinet.Switch knob 3 is arranged in order, and is corresponding with signal lamp, be contained in rotary knob below.These elements can be contained on the guidance panel of contact cabinet by this layout, also can fit together these elements, do not add upper connecting terminal, use as a control device.
When needing the power supply of two-way power supply: the signal lamp X2 on controller both sides, normally-closed contact green light by 1QF, 2QF, and the signal lamp of middle contact cabinet can be not bright, (because of contact cabinet control power supply does not have) presses the switch knob of 1QF and 2QF respectively, by the switching of circuit breaker auxiliary contact, signal lamp X1 has electricity and glows.Bus contact this moment cabinet control power supply has electricity, and signal lamp X2 is by the normally-closed contact green light of QF.From the indication of signal lamp, can know that the two-way power supply divides the open shop power supply.If mistake is closed the switch knob of contact cabinet breaker, because of the connected normally-closed contact in parallel of 1QF and 2QF of closing circuit, (this moment is opened) circuit breaker can not close a floodgate, and has prevented two-way power supply paired running.
When the power supply of needs one road power supply has two kinds of situations:
1, controller has only one the tunnel electric indicator light green light is arranged, and by corresponding switch knob, breaker closing, signal lamp switches by auxiliary contact, glows.The signal lamp green light of bus if do not work, can be operated rotary knob at this moment, can then press the switch knob of circuit breaker, because there is a circuit breaker not close a floodgate, interlocking contact is closed, and closing coil X gets, breaker closing, signal lamp glows by the switching of auxiliary contact.From the indication of signal lamp, can know, power by one road power supply.
2, be converted to the power supply of one road power supply by the power supply of two-way power supply, go earlier to cut off a circuit breaker, if the middle signal lamp does not work, then operate rotary knob 2, and then press the switch knob of network interconnecting circuit.Otherwise, if recover the power supply of two-way power supply, disconnect bus earlier, all connected because of the closing circuit of two circuit breakers and got in touch with the normally-closed contact of cabinet breaker, prevent two-way power supply paired running, and then the switch knob that need put into operation by another road.
