Abstract
The utility model discloses a split type sealed high-voltage vacuum contactor, which is characterized in that: a vacuum arc extinguishing chamber, a conductor A, a fixing component and a conductor C are sealed in an insulating support; three insulating supports are fixed on a frame according to a space requirement respectively; the fixed end of the vacuum arc extinguishing chamber is fastened to the movable end of the conductor to be in flexible connection with the conductor B; a connecting rod passes through a contact spring and is also connected onto the movable end of the vacuum arc extinguishing chamber; a tripping spring is arranged between a driving plate and a mounting plate; both an electromagnetic coil and a tripping electromagnet are fixed on the mounting plate; and the mounting plate is fixed in the frame. The contactor has the advantages that: three-phase split type sealing is performed by adopting an APG (Alkyl Polyglucoside) epoxy resin sealing technology; the problem of mutual insulation between electrified devices after the vacuum contactor is assembled is solved; the split type contactor has small occupied space; the space can be adjusted according to requirements; and the contactor has the characteristics of high standardization degree, convenience in operation and maintenance and the like.
Description
Technical field
The utility model relates to a kind of split type high-pressure vacuum contactor that seals admittedly.In electric power system, protect and control various motor, transformer, capacitor, belong to the design and fabrication technology field of medium voltage switchgear equipment.
Background technology
In the high-voltage electrical apparatus technical field, AC high voltage vacuum contactor is a kind of three-phase alternating current indoor high-voltage vacuum switchgear at present.Usually as the critical piece in the high-voltage switch gear the complete sets of equipment, belong to a kind of control apparatus, can be used for the control that cut-offfing of equipment such as AC high-voltage motor, transformer, capacitor closed closing operation and industrial and mining enterprises, power plant even load circuit.The vacuum contactor that occurs on the market mostly is air insulation now, unenclosed construction, and the overall dimension precision is low, the properties of product less stable.Also mostly be the integral type fixed structure on version, underaction, interchangeability are relatively poor, just must all change by three-phase if there is a circuitry phase to go wrong.To join cabinet type degree of protection low for stationary structure when cabinet is joined by producer, and cabinet type complexity often causes producer to do bigger change to the cabinet type, and the degree of product standardization is low.
Summary of the invention
The utility model proposes a kind of split type high-pressure vacuum contactor purpose of sealing admittedly is to overcome
State defective, adopt the solid encapsulation technique three-phase split of APG epoxy resin to seal admittedly, spaced apart can be adjusted as requested, has the standardization level height, characteristics such as reliability height, handled easily and maintenance.
Technical solution of the present utility model: it is characterized in that vacuum interrupter and A electric conductor, fixed part, C electric conductor are enclosed in the insulation support admittedly, three insulation are supported and are separately fixed on the framework by the spaced apart requirement, the moved end of the fastening electric conductor of quiet end of vacuum interrupter links to each other with the B electric conductor by being flexible coupling, connecting rod passes on the moved end that touch spring also is connected vacuum interrupter, tripping spring is installed between drive plate and the mounting panel, solenoid, tripping electromagnet all are fixed on the mounting panel, and mounting panel is fixed in the framework.
Advantage of the present utility model is: product adopts the solid encapsulation technique three-phase split of APG epoxy resin to seal admittedly, and spaced apart can be adjusted as requested, has the standardization level height, characteristics such as handled easily and maintenance; The product structure novelty, complete function, dimensional accuracy height; Volume is little easy for installation; The epoxy resin APG technology that adopts has improved the insulation property and the reliability of product greatly.
