Description
Technical field
The utility model relates to a kind of electric equipment, particularly relates to a kind of indoor permanent magnetism fixed sealing type high-pressure vacuum breaker.
Background technology
Existing indoor vacuum circuit-breaker is arranged on vacuum interrupter and upper and lower outlet terminal in the letter of epoxy resin cover, the letter of this kind epoxy resin cover is not partly wrapped electrification in high voltage fully, still there is the influence of dust in air and moisture in the cover letter, so cause cover letter interior galvanic circle heat radiation relatively poor, thereby the fail safe and the reliability of influence operation; Its operating mechanism adopts spring operating mechanism on the other hand, comprise motor, gearbox, switching-on mechanism, switching-in spring, the sincere son of combined floodgate, making electromagnet, quadric chain, oil buffering and brake separating mechanism, tripping spring, the sincere son of separating brake, tripping electromagnet and rubber buffering etc., complex structure, part is many, the manufacturing process complexity, processing cost height, easy break-down, breaker reliability is relatively poor, thereby influences its useful life.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple in structure, easy for installation, and cost is low, dependable performance, long service life, and the indoor permanent magnetism fixed sealing type high-pressure vacuum breaker of miniaturization.
The indoor permanent magnetism fixed sealing type of the utility model high-pressure vacuum breaker comprises fixed sealing type arc control device, operating mechanism and transmission mechanism.Wherein, the fixed sealing type arc control device are by the epoxy resin housing, admittedly be enclosed in the vacuum interrupter in the epoxy resin housing, the last outlet terminal that is connected with the vacuum interrupter upper end, lower wire end that is connected with vacuum plate chamber lower end by connector, and the insulated tension pole that is connected with the vacuum interrupter lower end is formed; Operating mechanism is a permanent-magnet manipulating mechanism, and by casing, the permanent magnet mechanism and the control module that are arranged in the casing are formed.Permanent magnet mechanism comprises static iron core, is positioned at the operating coil of static iron core, is positioned at the moving iron core of operating coil, the permanent magnet between moving iron core and static iron core, and the pull bar that is connected with moving iron core; Transmission mechanism comprises the rotating shaft that is arranged in the casing, the one end is connected with rotating shaft, and the A quadric chain that is connected with pull bar in the permanent magnet mechanism by adapter sleeve simultaneously, the one end is connected with rotating shaft, the B quadric chain that the other end is connected with connecting lever, the other end of connecting lever is connected with insulated tension pole, and an end is fixed on the casing tripping spring that the other end is connected with connecting lever.
The operation principle of the indoor permanent magnetism fixed sealing type of the utility model high-pressure vacuum breaker is, when circuit breaker was in the separating brake position, the moving iron core of permanent-magnet manipulating mechanism was positioned at upper position, and no current passes through in the operating coil.When control module provides the combined floodgate order, operating coil is by the electric current of specific direction, this electric current produces the magnetic field identical with the permanent magnet magnetic field direction in the static iron core bottom, produce the magnetic field opposite on moving iron core top with the permanent magnet magnetic field direction, the suffered magnetic attraction in iron core upper end is reduced, when the electric current in the operating coil increases to certain value, counter-force greater than the suction and the tripping spring of upper end is arranged downwards with joint efforts, moving iron core moves downward, by quadric chain A rotating shaft is rotated counterclockwise, by quadric chain B and connecting lever insulated tension pole is moved upward again, thereby the contact on the vacuum interrupter is moved upward, realize closing a floodgate, at this moment, realizing under the permanent magnet magnetic force effect closes a floodgate keeps, and gives the tripping spring energy storage; When control module provides the separating brake order, pass through electric current in the other direction in the operating coil, this electric current produces the magnetic field opposite with the permanent magnet magnetic field direction in moving iron core lower end, the suffered magnetic force of iron core is reduced, and when downward the making a concerted effort during pulling force less than tripping spring of moving iron core, tripping spring clockwise rotates rotating shaft by connecting lever one end and quadric chain B, and iron core is moved upward through quadric chain A and adapter sleeve, simultaneously, the connecting lever other end drives insulated tension pole and moves downward, and realizes separating brake.
The indoor permanent magnetism fixed sealing type of the utility model high-pressure vacuum breaker advantage be simple in structure, parts reduce 80%, cost is low, miniaturization, good insulation preformance, safe and reliable, non-maintaining, long service life.Simultaneously, binding hours, the separating brake that can set control impuls easily by communication interface put in place time-delay and control under-voltage value etc. are convenient to Based Intelligent Control and operation.
