Description
Technical field
The present invention relates to electric equipment technology, particularly a kind of isolating switch.
Background technology
In electric power networks, in order to safety, need the electric equipment of charging operation and interruption maintenance or be in equipment blocking for subsequent use and come, therefore must have obviously visible, enough large cut-off point.Isolating switch uses in circuit as this cut-off point just, and to guarantee the safety run and overhaul, in addition, isolating switch is also for the switching device shifter as equipment or circuit.
Existing isolating switch generally includes housing and is positioned at the driving shaft of housing and working shaft etc., and wherein, driving shaft passes housing and is in transmission connection with outside operating grip.When operating described operating grip and making driving shaft rotate to the combined floodgate of driving shaft or open position, driving shaft moves working shaft by a series of mechanical conveyor and rotates, and at this moment can realize combined floodgate or the gate-dividing state of isolating switch; When operating described operating grip and making driving shaft continue from the closing position of the open position of driving shaft driving shaft dorsad the test position rotating an angle to driving shaft, driving shaft triggers auxiliary switch by a series of machine driving, at this moment can realize the test mode of isolating switch, namely simulate circuit condition when major loop is connected.
In order to avoid the misoperation of operating personnel, driving shaft should have significantly spacing between its open position and test position.Existing a kind of isolating switch, arranges a stop screw at the open position of operating grip, to stop operating grip to the test position action of operating grip, driving shaft rotation can be stoped like this to the test position of driving shaft; When needing test position operating grip being placed in operating grip, removed by stop screw, that removes operating grip is spacing, at this moment operates described operating grip and driving shaft can be made to rotate test position to driving shaft.
Existing isolating switch realizes from the state of opening a sluice gate to test mode or from test mode to the conversion of the state of opening a sluice gate, must be realized by dismounting or mounting limit screw, operate comparatively loaded down with trivial details, and, once stop screw is lost, then cannot open a sluice gate position to operating grip at it carries out spacing, and therefore, the reliability of product also needs further raising.
Summary of the invention
In view of this, the invention provides a kind of isolating switch, in order to improve isolating switch from the state of opening a sluice gate to test mode or from test mode to the operation ease of the state of opening a sluice gate, and improve the reliability of product further.
Therefore, according to one embodiment of the invention, provide a kind of isolating switch, comprising:
One housing, the inside of described housing has chute, the first stop part and the second stop part;
One elastic limit device, is slidably arranged in described chute, comprises guide part and compression unit, and described guide part has the first guiding surface mutually in angle and the second guiding surface, and described compression unit is limited between described guide part and described first stop part;
One driving shaft stretched out in described housing, comprise the swing arm of radially protruding, the first promotion inclined-plane and second that described swing arm has mutually in angle promotes inclined-plane, when described driving shaft from driving shaft open a sluice gate test position from position to driving shaft rotate time, described first promotes the first guiding surface described in slope driving makes described guide part compress described compression unit to described swing arm to be limited between described second guiding surface and described second stop part, when described driving shaft from the test position of driving shaft to driving shaft open a sluice gate position rotate time, described in described second promotion slope driving, the second guiding surface makes described guide part compress described compression unit to described swing arm and is limited in described first guiding surface side.
As can be seen from technique scheme, guide part due to elastic limit device has the first guiding surface mutually in angle and the second guiding surface, and the swing arm of driving shaft has mutually in angle first promotes inclined-plane and the second promotion inclined-plane, when driving shaft from driving shaft open a sluice gate test position from position to driving shaft rotate time, first promotes inclined-plane by promotion first guiding surface, guide part and then compress described compression unit until swing arm turns over extreme position is limited between the second guiding surface and the second stop part of enclosure interior, at this moment, when not applying actuating force, driving shaft is limited in the test position of driving shaft, otherwise, when driving shaft from the test position of driving shaft to driving shaft open a sluice gate position rotate time, second promotes slope driving second guiding surface, guide part and then compress described compression unit to swing arm and turn over extreme position and be limited in the first guiding surface side, at this moment, when not applying actuating force, driving shaft is spacing by the first guiding surface, cannot rotate the test position to driving shaft.Therefore, the embodiment of the present invention only needs to apply certain actuating force to driving shaft can realize isolating switch from the state of opening a sluice gate to test mode or from test mode to the transformation of the state of opening a sluice gate, operation is comparatively convenient, operating handle is comparatively clear, and do not need any parts of dismounting in operating process, the reliability of product is had been further upgraded.
Optionally, described compression unit is Compress Spring, and described guide part has spring base hole further, and described Compress Spring is arranged in described spring base hole.In this structure, guide part and compression unit are Split type structure, and easy to assembly, reliability is higher.
Described guide part also preferably has spacing stuck point further, and described spacing stuck point protrudes from the end face near the first stop part of described chute.Like this, when Compress Spring release can, promote guide part when the first stop part moves dorsad, spacing stuck point is limited in the end face near the first stop part of described chute, can prevent guide part from deviating from chute.
Or described compression unit is flat spring, the sheet metal bending structure that described guide part and described compression unit are integrated, the strip width of described guide part is greater than the strip width of described compression unit and is rigidity.In this structure, the sheet metal bending structure that guide part and compression unit are integrated, has processing cost lower, easy to assembly, the advantage of lighter in weight.
Preferably, described guide part and described compression unit are respectively symmetrical structure.Like this, no matter driving shaft opens a sluice gate from driving shaft the test position that position turns to driving shaft, or what turn to driving shaft from the test position of driving shaft opens a sluice gate position, stressed all more balanced in chute of elastic limit device, reliability is better, is conducive to the useful life of improving isolating switch product.
Preferably, described housing and described chute, described first stop part and described second stop part are formed in one.Further reduce the processing of whole isolating switch, assembly cost like this.
Preferably, described first stop part is the inwall of described housing.Like this, directly utilizing the inwall of housing as the first stop part, without the need to arranging the first stop part in addition, further saving processing, assembly cost.
