Description
Technical field
The utility model relates to a kind of high voltage isolation switch contact dismantling device, belongs to electric power apparatus examination technical field.
Background technology
At present, in conventional substation, 35kV outdoor high-voltage isolating switch is based on GW4 and GW5 type isolating switch, and these two kinds of isolating switch structures are simple, easy to maintenance.Isolating switch in order to ensure contact resistance and contact qualified, contact is often provided with the larger spring of elasticity.When contact needs dismounting to overhaul, manpower can only be relied on to push down contact head, touch spring is pressed off.This dismounting mode is easy to cause fingertip to be out of shape, and sometimes also can collapse and fly by fingertip, and threaten worker safety, this method wastes time and energy in a word, and fail safe has much room for improvement.
Summary of the invention
For solving the problem, the utility model provides a kind of high voltage isolation switch contact dismantling device, can easily be pressed off by touch spring, and the strength that saves time, fail safe are high.
The technical scheme that solution the utility model problem is taked is: a kind of high voltage isolation switch contact dismantling device, comprises the first tong arm, the second tong arm, slide bar, handle, gland, screw mandrel.
Described first tong arm is sleeved on slide bar, can move along slide bar, and tong arm head bends to the inside.
Described second tong arm is fixed on slide bar one end, and tong arm head bends to the inside.
Described gland is fixed on the slide bar other end, is carved with the internal thread corresponding with screw mandrel in gland.
Described handle is fixed in gland.
Described screw mandrel is through gland, and one end is connected with the first tong arm is active, and the other end is provided with handle.
The utility model provides a kind of high voltage isolation switch contact dismantling device, and structure is simple, easy to use, has saved manpower and man-hour, has improve safety work level and efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model uses schematic diagram.
Embodiment
As shown in Figure 1, a kind of high voltage isolation switch contact dismantling device, comprises the first tong arm 1, second tong arm 2, slide bar 3, handle 4, gland 5, screw mandrel 6.
Described first tong arm 1 is sleeved on slide bar 3, and can move along slide bar 3, tong arm head bends to the inside.
Described second tong arm 2 is fixed on sliding 3 bar one end, and tong arm head bends to the inside.
Described gland 5 is fixed on slide bar 3 other end, is carved with the internal thread corresponding with screw mandrel 6 in gland 5.
Described handle 4 is fixed in gland 5.
Described screw mandrel 6 is through gland 5, and one end is connected with the first tong arm 1 is active, and the other end is provided with handle 7.
During use, as shown in Figure 2, tong arm 1 and 2 of the present utility model is positioned over the correct position outside fingertip 8, turning handle 7 and drive the first tong arm 1 to move along slide bar 3, conducting rod 9 can be taken off from the flared section of fingertip after all fingertips 8 are by overall clamping.After having overhauled, recover the assembling that can complete contact by reverse procedure.
The utility model provides a kind of high voltage isolation switch contact dismantling device, and structure is simple, easy to use, has saved manpower and man-hour, has improve safety work level and efficiency.
