Description
(1) technical field
The present invention relates to sulfur hexafluoride gas density relay, relate in particular to the expansion tube type sulfur hexafluoride gas density relay switch vibration abatement of no oily shock type.
(2) background technology
Existing expansion tube type sulfur hexafluoride gas density relay is directly driven by push rod with the switch fork, expansion tube one end is fixedly connected on the holder, the other end is connected on the Connection Block, push rod is installed on the Connection Block, the switch fork is installed on the sensitive switch to drive sensitive switch, sensitive switch is fixed on the holder, and push rod head correspondence the switch fork, does not have immediate constraint between the two.Run into when vibrations, be easy to generate the displacement disengaging between push rod and the switch fork, cause the relay fault and cause accident.
(3) summary of the invention
The object of the present invention is to provide a kind of sulfur hexafluoride gas density relay vibration abatement with the switch fork, this vibration abatement is by to the restriction between push rod and the switch fork, avoids being separated between the push rod and switch fork when shaking.
The present invention is achieved in that the vibration abatement of a kind of sulfur hexafluoride gas density relay with the switch fork, comprise push rod, switch fork, expansion tube one end is connected on the holder, the other end is connected on the Connection Block, push rod is installed on the Connection Block, the switch fork is installed on the sensitive switch to drive sensitive switch, sensitive switch is installed on the holder, it is characterized in that: the push rod head has groove, have strip hole on the switch fork, the push rod head recess is embedded in the switch fork strip hole and can moves with the driving switch fork along strip hole.
There is cylindrical boss at described push rod head recess two ends, and cylindrical boss clamps the switch fork that has strip hole.
Describedly the bimetal leaf temperature compensator is housed, Connection Block is housed on the temperature compensator in expansion tube one end.
Described sensitive switch can have a plurality of and be installed in parallel on the holder, and the respective switch fork also has a plurality of, and a plurality of push rods of parallel installation are to drive corresponding switch fork on Connection Block.
The present invention has groove at the push rod head, has strip hole on the switch fork, realizes between the two constraint by the cooperation in the push rod head recess flush switch fork strip hole, avoids being separated between the push rod and switch fork when vibrations.The present invention is simple in structure, practical, and is easily manufactured.
(4) description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the sulfur hexafluoride gas density relay structural representation that switch fork vibration abatement of the present invention is installed, and simplifies among the figure and has removed dial plate, the connecting rod of pointer and driving pointer, parts such as gear.
Fig. 2 is that local axle of the present invention is surveyed schematic diagram;
Fig. 3 is that the axle of push rod and the combination of switch fork is surveyed schematic diagram;
Fig. 4 surveys schematic diagram for the axle that the switch fork is expanded distortion.
Among the figure: 1 Connection Block, 2 switch forks, 3 holders, 4 sensitive switches, 5 push rods, 6 expansion tubes, 7 strip holes, 8 cylindrical bosses, 9 grooves, 10 bimetal leaf temperature compensators, 11 nuts.
(5) embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of sulfur hexafluoride gas density relay vibration abatement of switch fork, comprise push rod 5, switch fork 2, expansion tube 6 one ends are connected on the holder 3, the other end is connected on the Connection Block 1, and push rod has screw thread for 5 one sections, is installed on the Connection Block 1 through nut 11 lockings, switch fork 2 is installed on the sensitive switch 4 to drive sensitive switch 4, and sensitive switch 4 is installed on the holder 3.Push rod 5 heads have groove 9, have strip hole 7 on switch fork 2, and push rod 5 head recess 9 are embedded in switch fork 2 strip holes 7 and can move along strip hole 7, so also can realize cooperating of push rod head and switch fork; An embodiment also has cylindrical boss 8 at groove 9 two ends preferably, and push rod 5 head cylindrical bosses 8 clamp the switch fork 2 that has strip hole 7; The displacement of expansion tube 6 can drive Connection Block 1 like this, and Connection Block 1 drives the swing that moving up and down of push rod 5 heads can driving switch fork 2, thereby drives sensitive switch 4.
Sulfur hexafluoride gas density relay generally also is equipped with bimetal leaf temperature compensator 10 in expansion tube 6 one ends, can Connection Block 1 be housed on temperature compensator 10, and push rod 5 is housed on the Connection Block 1.
Referring to Fig. 3, sensitive switch 4 can have a plurality of and be installed in parallel on the holder 3, and respective switch fork 2 also has a plurality of, and a plurality of push rods 5 of parallel installation are to drive corresponding switch fork 2 on Connection Block 1.
Referring to Fig. 4, switch fork 2 is a sheet metal, when placing push rod 5, earlier strip hole 7 is extended to and the cylindrical boss 9 of push rod 5 can be inserted by shape shown in Figure 4, again strip hole 7 finishings are returned to original flat form after placing push rod 5, this is a kind of mode.Also can have screw hole, the cylindrical boss 8 of push rod 5 heads is fixed on push rod 5 heads, realize switch fork 2 is installed in push rod 5 grooves 9 by screw at push rod 5 apical heads.
The present invention is by to the restriction between push rod and the switch fork, avoided being separated between the push rod and switch fork when shaking.The present invention is simple in structure, practical, and is easily manufactured.
