Through the adding of the joint, the changing of the pulling rod into the screw rod, the clipping and fixing the joint by an upper and a lower adjustment nuts and the technical scheme of connecting the joint with the arm-link, thus making the connection between the pulling rod and the arm-link adjustable, the utility model adjusts the axial direction of the pulling rod without disassembling any parts.
Description
Technical field
The utility model belongs to the indoor high-voltage vacuum circuit breaker of a kind of control and protection electric equipment, especially relates to ZN63A-12 (VS1) the type easy adjusted type indoor high-voltage vacuum circuit breaker that a kind of electric information that is fit to the needs frequent operation uses.
Background technology
Existing ZN63A-12 (VS1) type indoor high-voltage vacuum circuit breaker is three-phase alternating current 50Hz, and rated voltage is the indoor high-voltage vacuum circuit breaker of 12kV.Its structure comprises cabinet, operating mechanism, vacuum interrupter, insulating cylinder, insulated tension pole and connecting rod thereof etc., the vacuum interrupter vertical direction is installed in the top in the insulating cylinder, the moving bar of its lower end is fixedlyed connected with insulated tension pole through connecting rod, insulated tension pole is made up of insulator and pull bar two parts, and the connecting lever in pull bar bottom and the operating mechanism is fixedly connected through bearing pin.The problem that prior art exists is: when the undesirable needs of the parameter of vacuum circuit breaker are adjusted, because insulated tension pole and vacuum interrupter all are installed in the insulating cylinder, need dismantle upper flange, outlet seat up and down successively, and can adjust connecting rod after the coupling pin of insulated tension pole bottom taken off, whole unloading process bothers very much, and the efficient that wastes time and energy is low.Non-adjustable just because of insulated tension pole to parts processing with equippedly proposed very high requirement, if once assembling can not meet the demands, make troubles for the vacuum circuit-breaker parameter adjustment.
Summary of the invention
For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of easy adjusted type indoor high-voltage vacuum circuit breaker with new structure, when the undesirable needs of the parameter of vacuum circuit breaker are adjusted, the circuit breaker of this structure does not need to dismantle any parts, just can adjust easily.
For achieving the above object, the utility model has adopted following technical scheme: the structure of this easy adjusted type indoor high-voltage vacuum circuit breaker comprises operating mechanism, vacuum interrupter, insulating cylinder, insulated tension pole and connecting rod thereof, vacuum interrupter is vertically in being installed in insulating cylinder, insulated tension pole is made of whole insulator and pull bar two parts, the moving bar of vacuum interrupter is through connecting rod and insulator top attachment, pull bar connects with connecting lever in the operating mechanism, it is characterized in that: pull bar is a screw rod, two adjusting nuts and a coupling head have been nested with on the screw rod, in the middle of two adjusting nuts were interposed in coupling head, the two ends of coupling head connected with connecting lever; Be provided with the adjusting window with matching part, adjusting nut installation site.
During concrete enforcement, coupling head shape middle part is square, has the through hole that is complementary with the pull bar diameter on the square body, and two ends are circular bearing pin, and bearing pin is provided with location notch.
During concrete enforcement, regulate window and be located on the frame of insulating cylinder bottom, its shape is the bar-shaped trough shape.
Beneficial effect: the utility model compared with prior art, pull bar of the prior art is provided with pin-and-hole, pin-and-hole coupling on this pin-and-hole and the connecting lever is sold and directly is fixed and is connected, and makes the adjustment of insulated tension pole axial location need dismantle a lot of parts, and is very inconvenient.The utility model is by setting up coupling head, and make pull bar into screw rod, insert and put the head that is fixedly connected by upper and lower two adjusting nuts, coupling head and connecting lever go the connection technique scheme, make pull bar become adjustable the connection, reached and do not dismantled the purpose that any parts just can be adjusted the pull bar axial location with the connection of connecting lever.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of an embodiment of the utility model;
Fig. 2 is the structure for amplifying schematic diagram of A portion among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.Sequence number is represented respectively among the figure: cabinet 1, and insulating cylinder 2, upper flange 3, last outlet seat 4, vacuum interrupter 5, following outlet seat 6, moving bar 7, insulator 8, pull bar 9 is regulated window 10, coupling head 11, adjusting nut 12, connecting lever 13.
Referring to Fig. 1, Fig. 2, the operation principle and the prior art of this circuit breaker are in full accord, do not remake further expansion explanation at this.
The innovative point that the utility model is made is to change the pull bar in the insulated tension pole and the connecting relation of connecting lever.The structure of this easy adjusted type indoor high-voltage vacuum circuit breaker comprises operating mechanism, vacuum interrupter 5, insulating cylinder 2, insulated tension pole and connecting rod thereof, vacuum interrupter 5 is vertically in being installed in insulating cylinder 2, insulated tension pole is made up of insulator 8 and pull bar 9 two parts, and both are the single piece that bond together.The moving bar 7 of vacuum interrupter 5 spins through connecting rod and insulator 8 screw top.Pull bar 9 is a screw rod, has been nested with two adjusting nuts 12 and 11, two adjusting nuts 12 of a coupling head on the screw rod coupling head 11 is interposed in the centre, and the two ends of coupling head 11 are sold with connecting lever 13 and connected; Be provided with adjusting window 10 with matching part, adjusting nut 12 installation site, can utilize instrument such as spanner to come turn adjusting nut 12 through regulating window 10 staff, there is not screw thread on the through-hole wall of coupling head 11, pull bar 9 can freely be shifted, therefore, adjust the axial location of adjusting nut 12 on pull bar 9, just can adjust the axial location of insulated tension pole and the connecting rod that links with insulated tension pole, moving bar 7, to change contact position in the vacuum interrupter 5.
During concrete enforcement, coupling head 11 shapes middle part is square, has the through hole that is complementary with the pull bar diameter on the square body, and does not have screw thread on the through-hole wall, and two ends are circular bearing pin, and bearing pin is provided with location notch.When circular bearing pin inserts in the corresponding pin shaft hole on the connecting lever 13, through location notch by finger setting.
