Embodiment shall fall within the protection scope of the present invention.
Fig. 1-6 is please referred to, includes a kind of improvement shape GN30 disconnecting switch, including support frame 1, insulating base 2, dynamic touching in diagram
First 3 and static contact 4, the insulating base 2 is equipped with multiple, and is equidistantly uniformly fixed on 1 top and bottom of support frame, the dynamic touching
First 3 and static contact 4 be equipped with it is multiple and fixed with multiple insulating bases 2 respectively.
Static contact 4 is made of static connection seat 5, support plate 6, U-shaped connecting plate 7, bolt 8, connecting spring 9 and thread cap 10,
The static connection seat 5 is installed in insulating base 2, there are two the support plate 6 is set, and symmetrical is fixed on 5 liang of static connection seat
Side, there are two the U-shaped connecting plate 7 is set, and it is symmetrical be fixed on two support plates, 6 top, the movement of bolt 8 is successively passed through
Two U-shaped connecting plates 7 are worn, and are threadedly coupled with thread cap 10,9 sets of the connecting spring in bolt 8 far from 10 one end of thread cap
Outside, and 9 both ends of connecting spring are fixed respectively at U-shaped connecting plate 7 and 8 one end of bolt, by by static connection seat 5 and insulating base 2
Fixation keeps static contact 4 more stable, is not in the tendency rotated around bolt.
Bolt 8 is cased with cushion block 11 on the outside of 10 one end of thread cap, and 11 outside of cushion block respectively with U-shaped connecting plate 7 and spiral shell
Line cap 10 contacts, and connect bolt 8 with U-shaped connecting plate 7 by cushion block 11 more stable, is also prevented from the damage U-shaped of thread cap 10 company
Fishplate bar 7.
Specific implementation method: when opening a sluice gate, at this time by rotation thread cap 10, it is detached from thread cap 10 and bolt 8, together
When, extract cushion block 11 out, then pull and push pin 8 outward, be clamped bolt 8 no longer with touch panel 16, then take out touch panel 16 realize GN30 every
Opening a sluice gate for pass is left, similarly when closing a floodgate, 16 one end of touch panel is placed between two U-shaped connecting plates 7, while being inserted into bolt 8, is made
Another U-shaped connecting plate 7 is run through in 8 one end of bolt, and puts on cushion block 11 and tighten thread cap 10 again, realizes and closes a floodgate.
Refering to fig. 1-6, in diagram moving contact 3 by dynamic attachment base 12, snap-gauge 13, shackle member 14, T shape connecting plate 15 and touch panel
16 compositions, the dynamic attachment base 12 is fixed on 2 top of insulating base by screw, and dynamic attachment base 12 is L shaped plate structure, institute
State there are two snap-gauge 13 sets, and it is symmetrical be fixed on dynamic 12 one end of attachment base, described dynamic 12 one end of attachment base is provided with connector
17, and T shape connecting plate 15 and connector 17 are clamped, described 16 one end of touch panel and T shape connecting plate 15 are fixed, and the other end and stationary contact
First 4 connection, there are two the shackle member 14 is set, and it is symmetrical be fixed on dynamic 12 one end of attachment base, pass through and change moving contact 3
Structure disassembles touch panel 16, close a floodgate open a sluice gate often after can directly dismounting and change damage touch panel 16.
T shape connecting plate 15 is symmetrically fixed with two card adapter plates 18 far from 16 one end of touch panel, and opens in two card adapter plates 18
There is limit hole 19, bayonet 20 is provided in the snap-gauge 13, and card adapter plate 18 and bayonet 20 are clamped, and pass through card adapter plate 18 and bayonet 20
Connecting and fixing to T shape connecting plate 15 is realized in clamping.
Shackle member 14 is made of sliding sleeve 21, traveller 22, U-shaped fixed plate 23, limit plate 24 and clamping spring 25, the sliding sleeve
The sliding of 21 one end is clamped through dynamic attachment base 12, and with limit hole 19, and the sliding sleeve 21 is slidably socketed far from 19 one end of limit hole
In 22 outside of traveller, and traveller 22 is fixed far from 21 one end of sliding sleeve and U-shaped fixed plate 23, the U-shaped fixed plate 23 and dynamic connection
12 outside of seat is fixed, and the limit plate 24 is fixed on sliding sleeve 21 far from the outside of 19 one end of limit hole, and 25 sets of the clamping spring exists
22 outside of traveller, and be clamped 25 both ends of spring and fixed respectively at U-shaped fixed plate 23 and limit plate 24, pass through the realization pair of shackle member 14
The limit up and down of T shape connecting plate 15.
Sliding sleeve 21 is bevel structure far from 22 one end of traveller, and 18 bottom of card adapter plate is bevel structure, is convenient for card adapter plate 18
With the connection between sliding sleeve 21.
Specific implementation method: a period of time, when switching number is excessive, touch panel 16 and U are used in GN30 disconnecting switch
It is excessive that Rubbing number is contacted between shape connecting plate 7,16 surface of touch panel can be made to wear, at this point, separate by pressing sliding sleeve 21
22 one end of traveller is clamped sliding sleeve 21 with limit hole 19, while lifting extraction T shape connecting plate 15 upwards, to make card adapter plate
18 are detached from bayonet 20, are no longer clamped with bayonet 20, complete the disassembly to touch panel 16, when installing new touch panel 16, at this point, by T
Shape connecting plate 15 is inserted into connector 17, and card adapter plate 18 is made to be inserted into bayonet 20 simultaneously, is clamped with bayonet 20, in the process of insertion
In, since the bottom of card adapter plate 18 and sliding sleeve 21 are bevel structure far from 22 one end of traveller, during two contact of incline plane,
Under the action of external force, sliding sleeve 21 can be made mobile to 22 one end of traveller, so that card adapter plate 18 be allowed to be fully inserted into bayonet 20, passed through at this time
It is clamped 25 elastic deformation of spring and generates elastic force, sliding sleeve 21 is pushed to be displaced outwardly, so that sliding sleeve 21 be made to be clamped to limit hole 19, complete
The limit of T shape connecting plate 15 is fixed, to realize to one of new touch panel 16 installation, the present invention is by will be on moving contact 3
Touch panel 16 be changed to detachable structure, thus when making to wear between touch panel 16 and U-shaped connecting plate 7 in operation, directly
It connects disassembly touch panel 16 and replaces the new touch panel 16 of installation again, do not need to replace entire moving contact 3, make to replace step
It is more convenient also to save cost.
Bolt 8 makes to adjust more convenient far from anti-skid chequer, increasing friction force is carved on the outside of 10 one end of thread cap.
Moving contact 3 and static contact 4 are all made of 99.99% copper plate of purity (T2) press shaping die, and silver-plated in its surface
Processing, the present invention are increased by changing moving contact 3 and static contact 4 etc. using 99.99% copper plate of purity (T2) press shaping die
The through-current capability of conductor reduces temperature rise, and in 4 table of moving contact 3 and static contact to reduce the heat generated when switch operation
Face silver-plated process, and silver coating thickness is no less than 20 μm, selecting the good material of heat-conductive characteristic is the radiator of conductor, from
And guarantees the temperature rise of conductor (red copper part) to meet as defined in standard and require.
