Abstract
The utility model discloses an outdoor isolation switch mechanical locking device of a transformer station in the technical field of electrical equipment. The outdoor isolation switch mechanical locking device of the transformer station comprises an L-shaped clamping groove plate with a shaft sleeve and an L-shaped clamping plate with a shaft pin, the L-shaped clamping groove plate is welded on an operating mechanism base of an isolation switch, the shaft pin of the L-shaped clamping plate can be inserted into the shaft sleeve of the L-shaped clamping groove plate, the L-shaped clamping groove plate and the L-shaped clamping plate are respectively provided with open locking holes, and the two open locking holes coaxially correspond with each other when the shaft pin of the L-shaped clamping plate is inserted into the bottom of the shaft sleeve of the L-shaped clamping groove plate. The device has the advantages of the simple structure, flexible operation, high safety and high reliability, and the isolation switch can be fully locked.
Description
Technical field
The utility model belongs to electrical equipment technical field, is specifically related to a kind of outside transformer substation isolating switch mechanical anti-misoperation locking device.
Background technology
Outside transformer substation isolating switch is all to adopt manual-operating mechanism substantially at present, its locking device does not generally have safeguard procedures, particularly some move ages transformer station of a specified duration, the mechanical locking device of its outdoor isolation switches is scraped and is drenched with rain at wind, under the condition of extraneous corrosion, the spring gross distortion of locking inside, and the internal corrosion of pin is very serious, and the internal clearance of original locking pin is too small, push rod screw is too short, jam phenomenon is serious, in the time of operation, be not drawn out easily especially, need screwdriver, the instruments such as pliers carry out back rotation, upwarp the difficult lockweight of extracting of lower hammer ability, sometimes can only adopt the method for destructive cutting, just can carry out grid switching operation, greatly incur loss through delay the grid switching operation time of electric equipment, the power supply reliability of impact to user.
utility model content
Waste time and energy in order to overcome existing substation isolating-switch mechanical locking device operation, incur loss through delay the grid switching operation time, affect the deficiency of power supply reliability, the utility model object is to provide a kind of use flexibly, reliably, has reduced the outside transformer substation isolating switch mechanical locking device of operations staff's grid switching operation time.
For achieving the above object, the technical solution adopted in the utility model: this outside transformer substation isolating switch mechanical locking device, it is characterized in that: comprise L-type clamping groove plate and a L-type clamp composition with pivot pin with axle sleeve, described L-type clamping groove plate is welded on the operating mechanism pedestal of isolating switch, the pivot pin of L-type clamp can insert in the axle sleeve of L-type clamping groove plate, on described L-type clamping groove plate and L-type clamp, be respectively equipped with switching lockhole, in the time that the pivot pin of L-type clamp inserts the axle sleeve bottom of L-type clamping groove plate two open and close lockhole coaxial pair should.
Adopt the beneficial effect of technique scheme: this outside transformer substation isolating switch mechanical locking device adopts the matched in clearance in axle sleeve and pivot pin gap, is beneficial to pin is extracted, free and relaxed when use, has good flexibility.Pass through to open and close lockhole by its locking with the anti-lockset of transformer station five again, be able to the object of safety interlocking.Isolating switch is firm in normal fixation in service, do not have shaking phenomenon, can meet the safety requirements of equipment grid switching operation, can make substation operation personal security, carry out fast, easily the grid switching operation of equipment, thereby alleviate operations staff's labour intensity.
brief description of the drawings:
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is isolating switch mechanical locking device section of structure.
Fig. 2 is the left pseudosection of Fig. 1.
Embodiment
Outside transformer substation isolating switch mechanical locking device as shown in Figure 1, 2, comprise that L-type clamping groove plate 2 and a L-type clamp 1 with pivot pin with axle sleeve forms, described L-type clamping groove plate is welded on the operating mechanism pedestal 4 of isolating switch, the pivot pin 5 of L-type clamp can insert in the axle sleeve 3 of L-type clamping groove plate, on described L-type clamping groove plate and L-type clamp, be respectively equipped with and open and close lockhole 6, in the time that the pivot pin of L-type clamp inserts the axle sleeve bottom of L-type clamping groove plate two open and close lockhole coaxial pair should.When use, the pivot pin of L-type clamp 15 is inserted in the axle sleeve 3 of interior L-type clamping groove plate, then with the anti-lockset of transformer station five by open and close lockhole 6 by its locking, be able to the object of safety interlocking.Isolating switch is firm in normal fixation in service, does not have shaking phenomenon, can meet the safety requirements of equipment grid switching operation.Can realize the locking completely of isolating switch.
