Abstract
A permanent magnetism operating mechanism for the high voltage vacuum circuit breaker. The utility model is comprised of an outer magnet yoke, a permanent magnet, an upper magnet yoke, a T-shaped armature iron, an operating rod, an inner magnet yoke, a dividing and connecting switch integral coil, a limiting sleeve, a bolt, a spring and a lower magnet yoke. A ring groove is arranged on the outer side surface of the inner magnet yoke. A construction groove is also arranged at the groove bottom of the ring groove. A step is arranged on the wall surface of the inner periphery of the outer magnet yoke. The limiting sleeve is installed at the upper part of the step of the inner periphery of the outer magnet yoke. The outer side of the permanent magnet embedded in the ring groove of the inner magnet yoke is fixed on the step of the inner periphery of the outer magnet yoke through the lower end surface of the limiting sleeve. The structure of the permanent magnetism operating mechanism for the high voltage vacuum circuit breaker is simple, and the design is reasonable. The problem that the permanent magnetism or the dividing and connecting switch integral coil is damaged through the displacement of the inner magnet yoke is completely eliminated, the operation of the permanent magnetism operating mechanism for the high voltage vacuum circuit breaker is secure and reliable, and the failure rate is zero during the service life. The arranged construction groove is convenient for the installation and adjustment of the permanent magnet, and the product quality of the permanent magnetism operating mechanism for the high voltage vacuum circuit breaker is extremely improved.
Description
Technical field
A kind of essential electronic element.High-pressure vacuum breaker permanent-magnet manipulating mechanism in particularly a kind of power supplying and distributing equipment.
Background technology
In the high-voltage fence, for solving the problem that is beneficial to assembling and setting in the long-term safety use of vacuum circuit-breaker permanent-magnet manipulating mechanism energy and the permanent-magnet manipulating mechanism manufacturing, Chinese patent 02223115.3 " permanent magnet stage locate mode permanent-magnet manipulating mechanism " has provided a kind of concrete technical scheme.In this scheme, the inboard both ends of the surface of permanent magnet are embedded in the annular groove of inner yoke outer wall, and permanent magnet outer upper end face is positioned on the set step of outer yoke inwall.This scheme is owing to fail to be fixed in the permanent magnet lower surface (have and take with seccotine permanent magnet lower surface and the outer yoke inwall technology that is adhesively fixed), and the inner yoke lower surface contacts with divide-shut brake coil upper end face.Moving armature will overcome the gap (or seccotine is ineffective) that foozle forms through ten million time strenuous exercise up and down, drive inner yoke and move down, and damage the divide-shut brake coil, damage permanent-magnet manipulating mechanism.In addition, in this scheme, when manufacturing the high-pressure vacuum breaker permanent-magnet manipulating mechanism, permanent magnet is embedded in the later stage of annular groove work, because permanent magnet quantity increases, produce the reason of high-intensity magnetic field, manpower can't be adjusted the assembly quality of control permanent magnet at all, further causes vacuum circuit-breaker permanent-magnet manipulating mechanism product quality to descend.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind ofly with inner yoke and the fixed high-pressure vacuum breaker permanent-magnet manipulating mechanism of permanent magnet thereof, makes it be unlikely to damage because inner yoke moves.This high-pressure vacuum breaker permanent-magnet manipulating mechanism is when manufacturing, and its permanent magnet is in the installation later stage of inner yoke outer surface annular groove, but the people is the influence that overcomes strong magnetic force, adjusts the installation of permanent magnet, strict guarantee product quality.
Of the present utility modelly, prior art is achieved by being improved.High-pressure vacuum breaker permanent-magnet manipulating mechanism of the present utility model contains the inner yoke of peripheral zone annular groove, interior week outer yoke with the level, divide-shut brake one body coil, T type armature and actuating bar, it is characterized in that a stop collar is equipped with on Zhou Taijie top in the outer yoke, be arranged on the permanent magnet in the inner yoke annular groove, its outside is fixed in the confinement groove that is formed by Zhou Taijie upper surface in stop collar lower surface and the outer yoke.
Described inner yoke also is provided with a construction groove at the trench bottom of its periphery annular groove.
High-pressure vacuum breaker permanent-magnet manipulating mechanism of the present utility model is simple in structure, reasonable in design.Eliminated the inner yoke that produces because of manufacturing tolerance formation fit-up gap and moved, and damaged permanent magnet or divide-shut brake one body coil problem, made the high-pressure vacuum breaker permanent-magnet manipulating mechanism safe and reliable, the zero failure rate has been arranged in the lifetime.The construction groove that is provided with has made things convenient for the installation and the adjustment of permanent magnet, has improved the product quality of high-pressure vacuum breaker permanent-magnet manipulating mechanism greatly.

Embodiment
Referring to accompanying drawing 1～3.High-pressure vacuum breaker permanent-magnet manipulating mechanism of the present utility model is made up of outer yoke 1, permanent magnet 2, upper magnet yoke 3, T type armature 4, actuating bar 5, inner yoke 6, divide-shut brake one body coil 7, stop collar 8, bolt 9, spring 10, lower yoke 11.Inner yoke 6 lateral surfaces are provided with an annular groove a.Trench bottom at annular groove a also is provided with a construction groove b.Outer yoke 1 is round barrel shape, and the internal perisporium face is provided with a step c.Permanent magnet 2, upper magnet yoke 3, T type armature 4, inner yoke 6, divide-shut brake one body coil 7 are installed in the inside of outer yoke 1.Stop collar 8 is installed in the top of Zhou Taijie c in the outer yoke 1.Be embedded in the permanent magnet 2 among the inner yoke 6 outside annular groove a, its outside is fixed on the upper end of Zhou Taijie c in the outer yoke 1 by the lower surface of stop collar 8.Divide-shut brake one body coil 7 is in inner yoke 6 below permanent magnet 2.The heart and the actuating bar 5 of T type armature 4 are fixed together, and the ring that outside wall surface is in inner yoke 6 in the heart.Be sleeved on spring 10 upper ends on the actuating bar 5 be sitting in T type armature 4 below, the lower end be sitting in lower yoke 11 above.Upper magnet yoke 3, lower yoke 11 and positioning sleeve 8 all are fixed together by bolt 9 and outer yoke 1.When manufacturing the high-pressure vacuum breaker operating mechanism, in the ordering that construction groove b place adjusts permanent magnet 2, make it to improve the quality of products with specific purpose tool.
Use this high-pressure vacuum breaker operating mechanism, during electric switch-on, impose on the magnetic force of the pulse current generation of divide-shut brake one body coil 7, make T type armature 4 overcome the elastic force of spring 10, move downward terminal adhesive and maintenance.4 whiles of T type armature this moment clap with the fitting surface of inner yoke 6 and lower yoke 11 and close.During electronic separating brake, impose on the magnetic force that the reverse impulse electric current of divide-shut brake one body coil 7 produces, make T type armature 4 under the acting in conjunction of the elastic force of magnetic force and spring 10, move upward to terminal adhesive and maintenance.The fitting surface of the last fitting surface of T type armature 4 and upper magnet yoke 3 is clapped and is closed at this moment.
