Embodiment
Referring to figs. 1 through Fig. 5, the utility model ring main unit pressure-operated load switch embodiment is described further.
A kind of ring main unit pressure-operated load switch, comprises framework 1, is fixed on upper insulation column 2 on framework 1 and lower insulation column 3, the vacuum switch pipe holder 4 being fixed on each insulation column outboard end, vacuum switch tube 5 and operating mechanism 6; Described operating mechanism 6 comprises the moving contact 61, articulated linkage 62 and the fixed lever 63 that are connected with its vacuum switch tube 5, and described fixed lever 63 is fixedly installed on framework 1 upper end; Described fixed lever 63 is arranged with spill spin block 64, so be provided with fixing spring 65 between spill spin block 64 and connecting rod; Described articulated linkage 62 one end is hinged by moving contact 61 and vacuum switch tube 5, and articulated linkage 62 other end is fixedly connected with fixing spring 65, and described operating mechanism 6 is provided with noise reducing mechanism.Described noise reducing mechanism is the reducing noise rubber layer 7 being wrapped in spill spin block 64 surface.Can effectively be reduced by the reducing noise rubber layer 7 being wrapped in spill spin block 64 surface because the sound sent when spill spin block 64 collides mutually with framework 1.
When an accident occurs; vacuum switch tube 5 will play corresponding effect; make hinge bar 62 can depart from moving contact 61 fast; spill spin block 64 can realize rotating fast; at this moment the reducing noise rubber layer 7 being wrapped in spill spin block 64 surface just effectively can play effect of protection and noise reduction; can either effectively prevent people from getting a fright, make the hommization more of ring main unit pressure-operated load switch.And by reducing noise rubber layer 7; can also effectively cushion the collision between spill spin block 64 and framework 1; while effective reduction sound; more effectively can reduce vibration, thus to framework 1, spill spin block 64 or even effectively protect whole ring main unit pressure-operated load switch.
Described noise reducing mechanism is also provided with sounding alarm mechanism 8, and described sounding alarm mechanism 8 comprises the elastic bag 81 with cavity, and described elastic bag 81 one end is fixedly connected with framework 1, and elastic bag 81 other end is fixedly installed on spill spin block 64 outer wall; Described elastic bag 81 is provided with air inlet 811 and gas outlet 813, is provided with intake valve 812 in described air inlet 811, is provided with air outlet valve 814 in described gas outlet 813, and described gas outlet 813 is connected with sounding whistle 82.Described air inlet 811 is also connected with sounding whistle 82.While spill spin block 64 can realize rotating fast, the meeting of the spill spin block 64 rotated presses elastic bag 81, make elastic bag 81 that deformation occur, thus the volume of elastic bag 81 can be reduced gradually, air in elastic bag 81 can be discharged along gas outlet 813, at this moment air inlet 813 will be in closure state because of the effect of intake valve 814, the air circulation that such elastic bag 81 occurs to produce when deformation volume reduces just only can be flowed out in gas outlet 813, the air of such flowing will drive the sounding whistle 82 be arranged on gas outlet 813 to sound, so just can allow can be more violent and very long by the air that whistle 82 occurs, sounding alarm mechanism 8 is made to send the duration longer, penetrability is better, more easily by the sound that it is found that.Can be convenient for people to by said apparatus and mechanism search out the ring main unit pressure-operated load switch had an accident fast, thus be convenient for people to keep in repair fast it and safeguard, what be convenient for people to completing circuit fast repaiies work by force, this makes it possible to save timely loss, avoid causing unnecessary loss.
After completing maintenance work as people, pull articulated linkage 62, make articulated linkage 62 can from being newly fastened on moving contact 61, such spill spin block 64 will from new spinning reduction, thus elastic bag 81 can be driven to open greatly from new support, in this process, gas outlet 813 will close by the air outlet valve 814 in gas outlet 813, and be exactly that air inlet 811 keeps clear, in like manner can draw, like this because elastic bag 81 because the air-flow that deformation produces will be independent pass through in air inlet 811, the air of such flowing will drive the sounding whistle 82 be arranged on air inlet 811 to sound, so just can allow can be more violent and very long by the air that whistle 82 occurs, sounding alarm mechanism 8 is made to send the duration longer, thus remind people's the utility model to be about to the operating state entered.
Support spring 83 is provided with in described elastic bag 81.By the effect of support spring 83 and can play a supporting role to the internal cavities of elastic bag 81, thus make elastic bag 81 can have larger deformation volume, thus make sounding alarm mechanism 8 can send the more lasting sound, conveniently people are more effectively guided; And by the effect of spring, can also make can be supported reset fast by the elastic bag 81 after compressing, can make sounding alarm mechanism 8 within the very first time, enter in operating state, make whole mechanism more reliably sensitive.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
