Abstract
A kind of post load switch auxiliary contact device, relates to outdoor pole top switch and distribution automation field.Comprise holder housing, motor, holder housing arranges a main shaft mounting panel, described motor is fixed on described main shaft mounting panel, motor output end is arranged on the side of main shaft mounting panel, the main body of motor is arranged on the opposite side of main shaft mounting panel, main shaft mounting panel arranges two auxiliary switches, auxiliary switch is arranged on the side that motor output end stretches out, a pressing plate is fixedly connected with at the output of motor, auxiliary switch is arranged on the both sides of described pressing plate, and the contact button of two auxiliary switches is respectively towards described pressing plate.The contact rating of this auxiliary switch is large, and with arc-suppression function, and auxiliary switch separates with high side switch and high-pressure side epoxy plate, ensure that low pressure and high pressure separately; Workpiece required for this auxiliary contact device only has installs straight plate, and processing is got up also fairly simple, to needing boring just passable.
Description
Technical field
The utility model relates to outdoor pole top switch and distribution automation field.
Background technology
In recent years, along with developing rapidly of intelligent grid, medium-sized manual on-pole switch just slowly replace by intelligent on-pole switch, post load switch is the one of intelligent on-pole switch, be mainly used to cut off rated load current; The auxiliary contact device of conventional on-load switch is mounted in above motor shaft, and realized the conversion of divide-shut brake auxiliary contact by the rotation of motor, the mode that this motor shaft switches auxiliary contact has some drawback:
1, the machining accuracy of motor shaft is higher, and existing auxiliary contact device switches auxiliary contact by motor shaft, motor shaft must mill out corresponding angle again;
2, auxiliary switch volume is smaller, inconvenient operation during mounting and adjusting, is difficult to the position controlling auxiliary switch reality;
3, unreliable when topmost problem is the auxiliary contact conversion of this mode, because motor is direct current permanent magnet motor, power is 120W, and inertia ratio during rotation is comparatively large, easily misses the position of groove milling on motor shaft, finally causes contact return contact bad.
Utility model content
In order to overcome above-mentioned drawback, the utility model provides a kind of post load switch auxiliary contact device.
The utility model comprises holder housing, motor, described holder housing arranges a main shaft mounting panel, described motor is fixed on described main shaft mounting panel, described motor output end is arranged on the side of described main shaft mounting panel, the main body of described motor is arranged on the opposite side of described main shaft mounting panel, described main shaft mounting panel arranges two auxiliary switches, described auxiliary switch is arranged on the side that described motor output end stretches out, a pressing plate is fixedly connected with at the output of described motor, described auxiliary switch is arranged on the both sides of described pressing plate, the contact button of described two auxiliary switches is respectively towards described pressing plate, described pressing plate is along with described electric machine rotation and press or unclamp auxiliary switch.
The utility model arranges epoxy dividing plate between described pressing plate and the main body of described motor, and described epoxy dividing plate is fixed in described holder housing.
Pressing plate described in the utility model is fixed on described motor output end by nut.
The utility model two described auxiliary switches are fixed on described main shaft mounting panel respectively by bolt, nut.
The utility model directly fills auxiliary contact conversion equipment on the main shaft of on-load switch, direct and on-load switch divide-shut brake interlock, and contact conversion is very clear and definite; Auxiliary switch is directly installed on main shaft mounting panel, and deciliter contact point signal directly rotates from main shaft and obtains, and not by other transmission links, improves the reliability of deciliter contact; Auxiliary switch mounting means is convenient and swift, is bolted on main shaft mounting panel directly by M10, is changed the stroke of auxiliary switch by the angle adjusting straight plate.The contact rating of this auxiliary switch is large, and with arc-suppression function, cycling is more than more than 5000 times.And auxiliary switch separates with high side switch and high-pressure side epoxy plate, ensure that low pressure and high pressure separately; Workpiece required for this auxiliary contact device only has one, installs straight plate exactly, and processing is got up also fairly simple, to needing boring just passable.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, this post load switch auxiliary contact device, comprise holder housing 1, motor 2, holder housing 1 arranges a main shaft mounting panel 3, motor 2 is fixed on main shaft mounting panel 3, motor output end 5 is arranged on the side of main shaft mounting panel 3, the main body of motor is arranged on the opposite side of main shaft mounting panel 3, main shaft mounting panel 3 arranges two auxiliary switches 4, auxiliary switch 4 is arranged on the side that motor output end 5 stretches out, a pressing plate 6 is fixedly connected with at motor output end 5, auxiliary switch 4 is arranged on the both sides of pressing plate 6, the contact button 7 of two auxiliary switches 4 is respectively towards pressing plate 6, pressing plate 6 is along with electric machine rotation and press or unclamp auxiliary switch 4.Arrange epoxy dividing plate 8 between pressing plate 6 and the main body of motor, epoxy dividing plate 8 is fixed in holder housing 1.Pressing plate 6 is fixed on motor output end 5 by nut 9.Two auxiliary switches divide 4 not to be fixed on main shaft mounting panel 3 by bolt 10, nut 11.
