Abstract
The utility model discloses an overtravel adjusting device for a vacuum switch contact. The overtravel adjusting device comprises a T-shaped sleeve, a contact spring, a lower tray and an adjusting cap, wherein an internal thread is arranged in the T-shaped sleeve, and the T-shaped sleeve is connected on a screw of an insulated driving rod of a vacuum switch in a threaded way; the contact spring and the lower tray are sleeved on the outer periphery of the T-shaped sleeve, and the contact spring is positioned between the T-shaped sleeve and the lower tray; the adjusting cap is arranged at the lower end of the T-shaped sleeve, and a pair of mutually matched flat openings are arranged in the outer periphery of the lower end of the T-shaped sleeve and the inner hole of the adjusting cap; a movable block sleeved on the outer periphery of the T-shaped sleeve is also arranged between the adjusting cap and the lower tray; and the movable block is connected with a driving crank arm of the vacuum switch. The overtravel adjusting device is simple in structure, can achieve the purpose of adjusting the overtravel and the synchronism of the vacuum switch contact by just rotating the adjusting cap, saves time and labor, relives the labor intensity, and improves the production efficiency. The overtravel adjusting device has no influence on the electric field of vacuum switch equipment, is beneficial to fusion welding resistance of the contact and is suitable for various types of vacuum switches.
Description
Technical field
The utility model relates to a kind of contact overtravel adjusting device in the vacuum switchgear.
Background technology
Vacuum interrupter is used more and more widely; The vacuum interrupter pole of rising in recent years is also increasing; But because pole all has only an end opening longitudinally usually; Can pass through this mouthful assembling conduction flexible link, transmission with parts such as insulated tension poles, and then whole end aligning switch frame with opening, install with the fastening completion of screw.Since the other end of insulated tension pole stretch into the narrow and small cabinet in space and must with transmission crank arm generation mechanical connection, often exist install, the unusual problem of difficulty of debugging.
The utility model content
The purpose of the utility model is to provide a kind of contacts of vacuum switch overtravel adjusting device, is connected problem difficult, that the contact overtravel is difficult to regulate to solve between vacuum switch insulating driving rod and transmission crank arm.
To achieve these goals, the utility model adopts following technical scheme:
A kind of contacts of vacuum switch overtravel adjusting device comprises T jacket tube, touch spring, following pallet, regulates cap; T jacket tube endoporus is provided with internal thread, and T jacket tube is threaded on the screw rod of insulating driving rod of vacuum switch; Touch spring is located at T jacket tube periphery with following tray sleeve, and touch spring is between T jacket tube and following pallet; The lower end of T jacket tube is equipped with one and regulates cap, and T jacket tube lower end periphery is provided with a pair of flat mouthful of cooperatively interacting with the endoporus of regulating cap; Regulate between cap and the following pallet and also be provided with the loose piece that is sheathed on T jacket tube periphery; Loose piece connects the transmission crank arm of vacuum switch.
The utility model further improves and is: regulating cap top is column type, and endoporus has flat mouthful; The bottom is outer six sides, and round tube hole in is arranged at bottom and top.
The utility model further improves and is: regulate cap and have the hex nut that is connected with screw flight.
The utility model further improves and is: loose piece and transmission crank arm flexibly connect.
The utility model further improves and is: vacuum switch also comprises frame, and frame is provided with main shaft, and main shaft is fixedly connected with transmission crank arm.
The utility model further improves and is: be installed with pole on the frame, pole has an endoporus, and insulating driving rod is passed the endoporus of pole.
With respect to prior art, the utlity model has following advantage:
1. simple in structure, used parts are with quite conventional;
2. owing to be installed in the earth potential end, the vacuum switchgear electric field is not influenced;
3. favourable to the anti-melting welding of contact, facts have proved that the lower end that touch spring is installed in insulated tension pole helps solving the contact welding problems;
4. be fit to various types of vacuum switches and use, be particularly useful for pole or solid isolated vacuum switch;
5. only needing turn to regulate cap can achieve the goal, and makes the contacts of vacuum switch overtravel regulate and becomes very simple, time saving and energy saving, reduces labor intensity, and enhances productivity.
Description of drawings
Fig. 1 is a kind of contacts of vacuum switch overtravel of the utility model adjusting device structural representation.
Wherein: 1 is T jacket tube, and internal thread hole is axially arranged, and the lower end has flat mouthful; 2 is touch spring; 3 are following pallet; 4 for regulating cap, and top is flat mouth for the column type endoporus has, and the bottom is outer six sides, and round tube hole in is arranged at bottom and top; 5 is hex nut; A is an insulating driving rod; B is a pole; C is a loose piece; D is a main shaft; E is a transmission crank arm; F is the screw rod with insulating driving rod A one; G is a frame; A～G belongs to vacuum switch self parts.
Embodiment
Specify the technical scheme of the utility model below in conjunction with accompanying drawing.
See also shown in Figure 1, a kind of contacts of vacuum switch overtravel of the utility model adjusting device by T jacket tube 1, down pallet 3, touch spring 2, regulate cap 4, hex nut 5 is formed.Touch spring 2 is installed between T jacket tube 1 and the following pallet 3; T jacket tube 1 endoporus has internal thread, is used for screwing in the screw rod F of vacuum switch insulating driving rod lower end, and T jacket tube 1 lower end is provided with flat mouthful; Regulate cap 4 endoporus and also be provided with flat mouthful; Just can drive T jacket tube 1 it is rotated on the screw rod F of vacuum switch insulating driving rod lower end through regulating 4 after both combine, reach the purpose of adjusting the contact overtravel very simply, also reach the purpose of adjustment synchronism simultaneously.
During practical implementation; Guarantee that earlier insulating driving rod A, pole B have connected reliably and can't rotate relatively; T jacket tube 1 is screwed among the screw rod F with insulating driving rod A one, again touch spring 2, pallet 3 is inserted in T jacket tube 1 down, with the hand rest pallet 3 of staying; Combinations thereof is installed on frame G and makes the lower end of T jacket tube 1 pass the loose piece C (loose piece C can rotate, and a vertical circular hole is arranged on the loose piece C) that is installed on the transmission crank arm E simultaneously on transmission crank arm E.Vacuum switch is closed a floodgate; Main shaft D remains on closing position after driving transmission crank arm E counter-clockwise swing certain angle; Loose piece C promotion simultaneously 3,2,1 moves upward; When the combined floodgate holding position, will regulate cap 4 be inserted in screw rod F tail end and make regulate cap 4 in flat mouthful combine with the outer flat mouth of T jacket tube 1 lower end; Block six sides that regulate cap 4 lower ends with spanner and also upwards hold gently, rotary spanner is measured loose piece C and is regulated the gap h between the cap 4 with feeler gauge simultaneously then, and making its numerical value that satisfies product technology condition regulation is the contact overtravel.After mixing up, it is fastening to load onto hex nut 5.
