Utility model content
The purpose of this utility model aims to provide and a kind ofly can guarantee the reliable contact of isolation earthing switch when closing at a high speed, and reduce the impact of moving knife kinetic energy to Drive Structure, and can guarantee the divide-shut brake circulation of 3000 times,
The quick retaining device of a kind of middle crimping of action message ground isolating switch disconnecting link still.
By the quick retaining device of a kind of middle crimping ground isolating switch disconnecting link of this object design, comprise moving knife, supporting bracket, conducting copper, fixed contact, bolster and air insulation switch, it is characterized in that being provided with in supporting bracket conducting copper, on conducting copper, be provided with fixed contact, on fixed contact, be provided with moving knife and bolster.
On described conducting copper, be provided with at least four screws, conducting copper is that metal material is made, and by welding or be riveted in supporting bracket; On described fixed contact, be provided with at least four through holes, fixed contact is fixedly connected with screw on conducting copper by screw, realizes the fixing of fixed contact and conducting copper.
On described fixed contact, be provided with tactile nose, tactile nose is connected on bolster and moving knife, makes moving knife realize open and close movement.
Described moving knife comprises two silver-plated conductive blades, fixing hole on conductive blade, and moving knife runs through the fixing hole on two conductive blades by disk spring assembly, realizes the clamping of two conductive blades and moving knife and touches being connected of nose on fixed contact.
The two ends head of described moving knife is arc-shaped structure, and resultant motion realize to be closed in one end, the other end be connected with tactile nose on fixed contact and its on be provided with two contacts and contact with bolster, realize cushioning effect.
On described bolster, be provided with deep-slotted chip breaker, bolster is connected on the tactile nose of fixed contact by deep-slotted chip breaker and bolster is arranged in supporting bracket and is fixedly connected with, and bolster is that polyurethane material is made.
Described air insulation switch is arranged in supporting bracket, and the top of air insulation switch is provided with moving knife.
In the utility model by contact is set on moving knife, bolster is fixed in supporting bracket by the tactile nose of fixed contact, when moving knife carries out quick crowbar motion, contact contacts with buffer stopper large area, has effectively realized the cushioning effect of isolation earthing switch when quick crowbar moves.Simultaneously its have simple and reasonable, cost is low, the feature such as easy for installation and safe and reliable.
Accompanying drawing explanation
Fig. 1 is the assembly structure schematic diagram of the utility model one embodiment.
Fig. 2 is the assembly structure schematic diagram of quick retaining device.
In figure: 1 is moving knife, 1.1 is contact, and 2 is supporting bracket, and 3 is conducting copper, and 4 is fixed contact, and 4.1 for touching nose, and 5 is bolster, and 6 is disk spring assembly.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Referring to Fig. 1-2, the quick retaining device of crimping ground isolating switch disconnecting link in this, comprise moving knife 1, supporting bracket 2, conducting copper 3, fixed contact 4, bolster 5 and air insulation switch 7, it is characterized in that being provided with in supporting bracket 2 conducting copper 3, on conducting copper 3, be provided with fixed contact 4, on fixed contact 4, be provided with moving knife 1 and bolster 5.
On conducting copper 3, be provided with at least four screws, conducting copper 3 is made for metal material, and by welding or be riveted in supporting bracket 2; On described fixed contact 4, be provided with at least four through holes, fixed contact 4 is fixedly connected with screw on conducting copper 3 by screw, realizes the fixing of fixed contact 4 and conducting copper 3.On fixed contact 4, be provided with and touch nose 4.1, touch nose 4.1 and be connected on bolster 5 and moving knife 1, make moving knife 1 realize open and close movement.Moving knife 1 comprises two silver-plated conductive blades, fixing hole on conductive blade, and moving knife 1 runs through the fixing hole on two conductive blades by disk spring assembly 6, realizes the clamping of two conductive blades and moving knife 1 and touches being connected of nose 4.1 on fixed contact 4.The two ends head of moving knife 1 is arc-shaped structure, and resultant motion realize to be closed in one end, the other end be connected with tactile nose 4.1 on fixed contact 4 and its on be provided with two contacts 1.1 and contact with bolster 5, realize cushioning effect.On bolster 5, be provided with deep-slotted chip breaker, bolster 5 is connected on the tactile nose 4.1 of fixed contact 4 by deep-slotted chip breaker and bolster 5 is arranged in supporting bracket 2 and is fixedly connected with, and bolster 5 is made for polyurethane material.
