The mini-type isolated automatic transfer switch has the advantages of simple structure, convenience in maintenance, low processing cost and the like.
Description
Technical field
The utility model belongs to isolated switching technique field, especially relates to a kind of miniature isolated automatic change-over.
Background technology
Abbreviate " double power supply automatic transfer switch " or " twin-power switch " in the electric utility as.The development of power supply switched system series products has been experienced three types substantially: contactor class, breaker of plastic casing class/load-break switch class, integral type automatic transfer switching electric appliance class.Automatic transfer switching electric appliance, i.e. ATSE (Automatic Transfer Switching Equipment).Forms by (or several) transfer switching equipment and other essential electrical equipment, be used to monitor power circuit and one or several load circuit is converted to the electrical equipment of another power supply automatically from a power supply, to guarantee that important load is continuous, reliability service.Therefore, ATSE is applicable to mainly that rated voltage exchanges and is no more than the emergency power supply system that 1000V or direct current are no more than 1500V, during conversion electric power, interrupts powering to the load.ATSE just undertakes automatic convert task, just selects PC level ATSE for use.PC level ATSE is the special switch that duplicate supply switches, have simple in structure, volume is little, self is chain, conversion speed fast (in the 0.2s), advantage such as safe, reliable, but needs outfit breaker protector.
The requirement of the current construction wall thickness of the big incompatibility of existing ATSE volume, the general shell of product can not fire-retardant color dullness.
The product standard of ATSE issued nearly 6 years, but in design is used, still ran into a lot of problems, also caused some accidents and loss.
According to the needs of present capital construction such as worker China Democratic National Construction Association, factory construction, infrastructure construction; Even the characteristics of the construction of national grid; Needing supporting equipment is the energy saving and environment friendly product that capacity is big, volume is little of parameter matching; Present product appearance volume is excessive, not attractive in appearance, can not satisfy the demand in market now.
Summary of the invention
The problem that the utility model will solve provides a kind of isolated automatic change-over, especially is fit to the matching used a kind of miniature isolated automatic change-over of generating equipment EPS emergency power plant.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of miniature isolated automatic change-over, comprise motor, dial, driving lever parts and isolating switch, and the axle of said motor is connected with the hole on the said dial;
Said isolating switch comprises convex shape and the isolating switch shell of chute is arranged; Main power source joint in isolating switch shell lower left; The plus screw of installing on the main power source joint; The isolating switch shell upper right with below be respectively stand-by power source joint and output electric weight joint; The main power source joint; The stand-by power source joint all passes through conductive metal sheet with output electric weight joint and is connected with double break contact; Two cams that are rotatably connected with the isolating switch shell; Carry the hurdle and be connected two torsion springs that the other end is connected with the isolating switch shell with corresponding cam for two that in the middle of two cams, connect with an end with corresponding cam;
Said carrying on the hurdle is equipped with two corresponding double break contacts through conductive metal sheet;
Said driving lever parts comprise that two Fang Gang, the end that pass two said cams are enclosed within two deflecting plates and two balancing arbors that are fixedly connected with two deflecting plate other ends on two square thick sticks;
Said two balancing arbors are installed in the dial both sides and are slidingly connected.
Further, the material of said isolating switch shell is fire-retardant Nylon 66 G30.
Further, said contact material is an Ag-ZnO.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, solved the bulky problem of existing like product, it is little to have developed volume; The product that divides broken height; Adopted the parallel connection double-breakpoint structure, double break point high sublevel technology switch adopts modular organization, guide tracked installation, the full inflaming retarding shell of different colours; Changed the single black shell of domestic like product; Aesthetic in appearance, the little requirement that is fit to current construction wall more of miniature volume, single motor operation is convenient; Have simple in structure, easy to maintenance, advantage such as processing cost is low.

Embodiment
Like Fig. 2,3,4,5, shown in 6 and 7, the utility model is a kind of miniature isolated automatic change-over, comprises motor 1, dial 17, driving lever parts and isolating switch 3, and the axle of said motor 1 is connected with the hole on the said dial 17; Said isolating switch 3 comprises that there is the isolating switch shell 7 of chute convex shape and lower end; Main power source joint 4 in isolating switch shell 7 lower lefts; The plus screw of installing on the main power source joint 4; Isolating switch shell 7 upper right with below be respectively stand-by power source joint 12 and output electric weight joint 13; Main power source joint 4; Stand-by power source joint 12 all passes through conductive metal sheet 6 with output electric weight joint 13 and is connected with double break contact 8; Two cams 10 that are rotatably connected with isolating switch shell 7; Carry hurdle 11 and be connected two torsion springs 9 that the other end is connected with isolating switch shell 7 with corresponding cam 10 for two that in the middle of two cams 10, connect with an end with corresponding cam 10; Said carrying on the hurdle 11 is equipped with two corresponding double break contacts 8 through conductive metal sheet 6; Said driving lever parts comprise that the square thick stick of two of passing two said cams 10 14, an end are enclosed within two deflecting plates 15 and two balancing arbors 16 that are fixedly connected with two deflecting plate 15 other ends on two square thick sticks 14; Said two balancing arbors 16 are installed in dial 17 both sides and are slidingly connected.Further, the material of said isolating switch shell 7 is fire-retardant Nylon 66 G30.Further, said contact 8 materials are Ag-ZnO.
The course of work of this instance: during work, a kind of control chip of miniature isolated automatic change-over control motor 1, motor 1 is through axle drive dial 17; Dial 17 drives the balancing arbor 16 of driving lever parts; Two square thick sticks 14 that balancing arbor 16 drives the driving lever parts rotate in the same way, and two square thick sticks 14 drive corresponding two cams, 10 rotations, and torsion spring 9 drives cam 10 rotational fixation moments of torsion; Thereby drive is carried hurdle 11 and is moved up and down, thereby reaches the purpose of synchronous conversion main power supply.The material of isolating switch shell 7 is fire-retardant Nylon 66 G30, and contact 8 materials are Ag-ZnO.Adopt the parallel double breakpoint, be two groups of contacts 8 up and down, improved the break-make index, dwindled the volume of product.A kind of miniature isolated automatic change-over has been realized small size, divides broken height.Double break point high sublevel technology switch is taked guide tracked installation, overall plasticization flame retardant type shell, and volume is little aesthetic in appearance.Can confirm the number (being generally four isolating switches) of isolating switch 3 as the case may be.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
