Abstract
The utility model discloses a switching on-off electric magnet. The coil end of the electric magnet is provided with a lug. Both ends of a connecting bar are provided with screw threads. One end of the connecting bar is connected with an armature. The other end of the connecting bar is provided with a nut and a copper pressing block. The connecting bar is sheathed with a soft gasket. Because the out extending end of the connecting bar of the utility model is provided with the copper pressing block and the soft gasket, the operation is stable and reliable, and the installation is convenient. The utility model is suitable for vacuum circuit breakers.
Description
The utility model relates to a kind of divide-shut brake electromagnet
In the framework of the divide-shut brake electromagnet that uses coil is installed now, is provided with guide pin bushing in the coil, the armature during energising in the guide pin bushing stretches out at the effect lower edge of electromagnetic force guide pin bushing; Under the effect of spring force, reset during outage, successfully be applied in the vacuum circuit-breaker; But the contact-making surface of finding the connecting rod outer end in using is little, less stable; In addition, owing to only lug plate is set at the left end of electromagnet, and use a plurality of divide-shut brake electromagnet in the vacuum circuit-breaker, for the divide-shut brake electromagnet wiring inconvenience that is installed in other position, also brought difficulty for maintenance.
The purpose of this utility model is to design the divide-shut brake electromagnet that nut and briquetting are equipped with in a kind of connecting rod of armature outer end in order to overcome above-mentioned deficiency; Stable working, installation, maintenance is convenient.
The utility model content, the two ends of the connecting rod of divide-shut brake electromagnet are shaped on screw thread, and an end of connecting rod is connected with armature, and the other end of connecting rod is equipped with nut and copper briquetting, and suit soft packing ring on the connecting rod, and overhang is provided with lug plate
The copper briquetting is provided with four directions, six sides or symmetrically arranged two planes that clamp usefulness for spanner, and the left end that lug plate can be located at coil also can be located at the right-hand member of coil.
The utlity model has following good effect:
1, because lug plate can be located at the left end or the right-hand member of coil as required,, assemble easy to maintenance so can be used for different position in the vacuum circuit-breaker.
2, because armature and connecting rod employing are threaded, are connected with used pin and compare, connect reliably, it is easy to make, install.
3, the connecting rod overhanging end is equipped with the copper briquetting, and the copper briquetting is good every magnetic property, and the face area of this copper briquetting is big, and it is steadily reliable to work together.
4, the position of copper briquetting on connecting rod can be carried out trace and adjusted, and adjusts the back and uses nut check, can prevent effectively that the copper briquetting from getting loose and be subjected to displacement.
5, the soft packing ring of connecting rod two can alleviate the bump and the vibration of this electromagnet, has reduced noise.
Description of drawings:
Fig. 1 is the utility model structural representation.
Further specify the utility model embodiment below in conjunction with accompanying drawing, the divide-shut brake electromagnet is made up of framework 1, spring 2, block 3, lug plate 4, armature 5, guide pin bushing 6, coil 7, straight lug plate 8, connecting rod 9, copper briquetting 10, nut 11 and soft packing ring 12.Some divide-shut brake magnet spool left ends are established a pair of lug plate 4, the right-hand member of other divide-shut brake electromagnet coils is established a pair of straight lug plate 8, can select for use lug plate to be located at the product of left end or right-hand member by the principle of easy-to-connect for the divide-shut brake electromagnet that is distributed in the diverse location in the vacuum circuit-breaker, the two ends of connecting rod all are shaped on screw thread, one end and the armature of this connecting rod are connected as a single entity by screw thread, and the assembling construction easily.The other end of connecting rod is equipped with copper briquetting and nut, and the position of copper briquetting on connecting rod can be regulated, and adjusts the back and uses nut check, mills out two facets in the present embodiment on the face of cylinder of copper briquetting symmetrically, and spanner clamps and uses during for locking.Soft packing ring is housed on the connecting rod, adopts rubber washer in the present embodiment, also can adopt plastics or other packing ring than softwood matter; Because during the electromagnet outage, armature sends bigger sound when resetting under the effect of spring force, after adding soft packing ring, reduced sound significantly, improved operational environment when deciliter electromagnet is switched on, effect lower armature in electromagnetic force stretches out, and drive connecting rod, the copper briquetting moves to right, switch on the pressing vacuum circuit-breaker (figure does not show), when the divide-shut brake electromagnet cuts off the power supply, under the elastic force effect of spring 2, armature is resetted and drive connecting rod, the copper briquetting moves to left, switch on the vacuum circuit-breaker also resets, unobstructed for armature is moved in guide pin bushing, on the armature cylindrical, be coated with last layer graphite or molybdenum bisuphide in the use, because the lubrication of graphite or molybdenum bisuphide, reduced the frictional force between armature and the guide pin bushing, even under lower voltage, armature also can move freely, has improved deciliter ability and the reliability of divide-shut brake electromagnet under low-voltage.
