Description
Technical field
The utility model belongs to the horizontal grafting isolating switch of electric power system mesohigh breaker technical field, particularly a kind of hand high voltage breaker.
Background technology
Handcart type breaker is applied to northern indoor substation more, and its structure is arranged on dolly by circuit breaker, and dolly is movable on fixing track.The fixed contact of isolating switch is installed on the insulator, isolates the moving contact cut-off and is arranged on the terminal block of circuit breaker, promotes dolly and drives circuit breaker and isolating switch moving contact to move, realize combined floodgate and the separating brake of isolating switch.General isolation switch contact is cylindrical structural, and fixed contact is bar-shaped, and moving contact is the Self-help contact terminal of milling lobe, or adopts secondary spring to provide the structure of contact terminal of contact force.But the required precision of this structure to assembling is very high, bad realization guiding, and insertion can not be too large, if insertion controls improper easy damage contact or causes loose contact to strike sparks.Need the position and the right position that adjust short transverse during adjustment insulating contact, process is loaded down with trivial details, wastes time and energy.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, and proposes the horizontal grafting isolating switch of a kind of hand high voltage breaker.
The utility model solves its technical problem and takes following technical scheme to realize:
The horizontal grafting isolating switch of a kind of hand high voltage breaker, it is characterized in that: comprise and be arranged on the moving contact tripod promoted on dolly and the fixed contact installing rack installed on the insulator, moving contact installation frame is fixed with on the right side of moving contact tripod, at the middle part of moving contact installation frame, fixed pin shaft is coated with by framework upper and lower plates hole, the two ends up and down of fixed pin shaft are fixed on framework upper and lower plates by bearing pin nut, the right plate of moving contact installation frame to be coated with on moving contact fingertip plate under fingertip plate and moving contact respectively by upper and lower hole, on, after the right-hand member of lower fingertip plate penetrates the right plate of framework, by upper, on the right side of lower fingertip plate, the perforation of termination is installed on described fixed pin shaft, upper in moving contact installation frame inside, between lower fingertip plate, fixed installation is with upper, the cylindrical Interposer contact of lower fingertip plate electrical connection, upper in moving contact installation frame outside, lower fingertip plate is shaped with perforation respectively, adjustment bearing pin is installed in perforation, regulating the spinning adjusting nut respectively of two ends up and down of bearing pin, adjusting nut with on, compression spring is installed respectively between the outer panel face of lower fingertip plate, the fixed contact hold-down arm of horizontal direction is fixed with in the left side of fixed contact installing rack, cylindric fixed contact is fixedly mounted with at the left end head of fixed contact hold-down arm, fixed contact and upper, lower fingertip plate middle opening is maintained at the same horizontal plane.
And in the right openings termination of described upper and lower fingertip plate, be all shaped with along the bandy radian section of open horizontal center line, the radius of the radian of described radian section correspondence is 2-3 times of described cylindric fixed contact radius.
And, between described adjusting nut and compression spring, be equipped with spring pad.
Advantage of the present utility model and good effect are:
This utility model provide a kind of newly, the isolating switch structure of horizontal movement, solve the problem of the horizontal grafting of handcart type breaker isolating switch.
Accompanying drawing explanation
Fig. 1 is system configuration schematic diagram of the present utility model.
