Description

All-In-One Electric Leakage Switch
The utility model relates to a kind of residual current circuit breaker, is that compactness is integral circuit breaker formula, electric operating energy automatic closing, can do the power distribution equipment of low voltage electric network, the critical component effect of emergency protective device.
Adopted earth leakage protective device in national upgrade of rural power grids; short circuit, overcurrent, electric leakage had defencive function; this class earth leakage protective device; for solving reclosing and automatic dropout problem, can divide three kinds to be combined to form substantially: the one, triplicity becomes the power distribution protection circuit with leakage relay for air switch, A.C. contactor.The 2nd, as the air switch of DW15 model the magnetic device is arranged, can directly combine with leakage relay, save A.C. contactor, both form the power distribution protection circuit.The 3rd, air switch, electric switch-on device and leakage relay are formed the power distribution protection circuit.From present assembling situation, which kind of combining form no matter, air switch in them, leakage relay, A.C. contactor or electric switch-on device, all independent separately, disperse to be installed on the distribution panelboard, connect with lead, be a kind of split type, this makes that the power distribution equipment volume is big, the layout complexity, and cost improves.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and designs and a kind of leakage relay is replaced with the relay air switch, and each sub-assembly is assembled into one, reduced the volume of power distribution equipment, layout is clear, lower-cost All-In-One Electric Leakage Switch.
The purpose of this utility model can realize by following measure: it is made up of air switch, zero-sequence transformer, tripping mechanism, leakage protection circuit and box body; the box body loam cake is covered with control panel and corresponding button hole, indicator lamp hole etc.; there is binding post at two ends; inner cap is arranged in the box body; this inner cap can be to cover formula; it also can be iris type; it is separated into chamber and following chamber with the box body inner room; the free-end of the handle of indoor air switch passes inner cap down; stretch to the chamber and link to each other with the controls of electric switch-on device, electric switch-on device links to each other with contacting controling circuit.
Of the present utility model employing all means available is: electric switch-on device is the device that screw mandrel combines with slide block, and screw mandrel one end directly or indirectly connects the motor projecting shaft, and slide block is a control member, and it links to each other with handle, the external screw thread of screw mandrel and the screw-internal thread fit of slide block.Drive the control member of handle, generally be installed in the chamber, and other rotating part of electric switch-on device can be by last chamber, following chamber or side.
Fig. 1 is the utility model structural representation.
Fig. 2 is a circuit block diagram of the present utility model.
Structure embodiment is described in detail below the utility model: the utility model can be divided into residual current circuit breaker; electric switch-on device; multiple chamber box body and several major parts of related circuit structure; motor in the electric switch-on device 6 can be a direct current machine; just also can be; the alternating current machine of reverse rotation; power supply can be a positive-negative power; or relay switches; circuit breaker is also because of the difference of its function; it can be residual current circuit breaker; it also can be phase failure circuit breaker; therefore protective circuit and contacting controling circuit should design as the case may be, the accompanying drawing 2 in the application's material be illustrative provided a kind of circuit block diagram of residual current circuit breaker of electric switch-on.
Motor projecting shaft in the electric switch-on device 6 links to each other with screw mandrel 4, be with slide block 3 on the bar silk 4, both internal and external threads match, rotating alternating current machine projecting shaft directly or indirectly connects screw mandrel 4, adopt can directly connecting of rotating deceleration synchronization motor, otherwise connect screw mandrel 4 again through deceleration device, motor rotating band movable wire bar 4 rotates, thereby make slide block 3 movable back and forth, affect coupled handle 5 combined floodgates and reset.Slide block 3 is movable spacing, is controlled by travel switch, optoelectronic switch, time switch, and complete combined floodgate, the homing action of a cover also has signal acquisition circuit, action decision circuitry etc. to finish common the cooperation.Wherein general leakage relay is replaced with relay electric leakage air circuit, cost descends.
Electric switch-on device can also adopt the wheel and rack device, and tooth bar links to each other with handle 5 to finish as controls and closes a floodgate and the moving part that resets.
By accompanying drawing 2 as seen: integral body of the present utility model is made up of air switch A, signal acquisition circuit B, dropout combined floodgate decision circuitry C, tripping mechanism D, the E of electric switch-on mechanism, power circuit F etc.Signal acquisition circuit is made of the curtage Acquisition Circuit, selects for use zero-sequence transformer to gather the residual current of air switch output loop; Dropout combined floodgate decision circuitry is the function difference, and circuit also has different.With earth leakage protective is example, by electric-leakage detection circuit IC 1, chip microprocessor IC 2, test button, trip push button, reset button, electric leakage show compositions such as ammeter; Tripping mechanism D is made up of electromagnet and dropout mechanical transmissioning piece, is used for the dropout operation of air switch; The E of electric switch-on mechanism is by the electric control circuit relay J 1, J 2, the motor M and the machinery that closes a floodgate constitute, and are used for the combined floodgate of air switch and reset; Power supply electrical equipment F supplies with power of alterating and direct current.
The residual current of the zero-sequence transformer direct proportion delivery air switch output loop in the accompanying drawing 2 is to IC 1, when line electrical leakage meets or exceeds rated value, IC 1Output signal is to IC 2, through IC 2Logic determines and time-delay control, output signal is triggered to controllable silicon SCR, after SCR is triggered, connects the release electromagnet electric power loop, and air switch is threaded off, and stops to export three phase mains.IC 2Also judge whether to carry out reclosing operation according to input/output state, during permission, output signal control J 2Suction is put, with the decision motor M just or the backward rotation direction, the J of output signal control simultaneously 1Suction was put with the decision motor M operating time, and the motor M rotation drives the closing device combined floodgate and resets.
Compound box body 1 is layout like this: following indoor storing air switch, zero-sequence transformer and tripping coil, handle 5 free-ends of air switch pass inner cap 7 and extend the chamber, link to each other with slide block 3, the integrated package of electric switch-on device 6, electric-leakage detection circuit, contacting controling circuit etc., can be installed in indoor, loam cake is covered with control panel 2 and corresponding hole, window etc., and there is the binding post 8 of turnover line at the two ends of box body.
The utility model can automatic closing and is resetted, and volume is small and exquisite to be integral, thereby has also reduced the power distribution equipment volume, makes the power distribution equipment layout clear, and cost is low, and is easy to use.
