Abstract
The utility model provides a 12KV outdoor high-voltage isolation switch which adopts a double-column vertical startup and three-phase with a common bottom rack type structure. The 12KV outdoor high-voltage isolation switch comprises an under frame, insulators which are installed on the under frame, conductive parts which are arranged on the upper parts of the insulators, and grounding knife switch operating mechanisms. The insulators present to be large and small umbrella-shaped structures. There are six insulators, and each phase is provided with two insulators. Each conductive part comprises a wiring board, a static contact, a moving contact knife switch and a contact seat. Further, the middle part of the under frame is provided with a close and separating switch operating rotating shaft which is connected with three operating insulators in a hinged way. The other ends of the operating insulators are connected with the middle parts of the moving contact knife switches of the isolation switch in the hinged way so that the operating rotating shaft is driven by a manual operating mechanism of the isolation switch to rotate from different directions, and thus the operating insulators are driven to move upwardly or downwardly to push out the moving contact knife switches to be separated or pull down the moving contact knife switches to be closed. The isolation switch is heavy in load current, great in heat stability and high in antifouling capability. Meanwhile, the isolation switch has characteristics of being simple in structure and convenient to operate.
Description
Technical field
This practicality relates to a kind of 12kV outdoor high-voltage isolating switch.
Background technology
High voltage isolator carries out changing-over or the electric equipments such as the high voltage bus being overhauled, circuit breaker and charged high-tension line is isolated having for high-voltage electric power circuit under voltage immunization with gD DNA vaccine, be widely used in the high pressure power transmission and distribution of three-phase electrical power system.Traditional 12kV high voltage isolator exists deficiency in the majority, particularly through-current capability to be difficult to do greatly on structure and material.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of through-current capability is strong, Heat stability is good, 12kV outdoor high-voltage isolating switch that antifouling grade is high, simultaneously simple in structure, easy to operate.
For achieving the above object, the utility model adopts a kind of like this 12kV outdoor high-voltage isolating switch, it adopts twin columns vertical unlocking, three-phase is chassis type structure altogether, comprise underframe, be arranged on the insulator on underframe, be arranged on current-carrying part and the earthing switch blade operating mechanism on insulator top, described insulator is big or small beveled structure, arrange altogether 6, 2 of every phases, described current-carrying part comprises terminal block, fixed contact, moving contact plug-in strip and contact base, further arrange, moving contact plug-in strip is set to two conducting strips that structure is identical, one end of moving contact plug-in strip is hinged by being installed with bolt and the contact base on insulator of Compress Spring, another free end fits two conducting strips to be integrated by being installed with the bolt of Compress Spring, fixed contact clamping when isolating switch closes a floodgate and on another insulator, like this, the Compress Spring that moving contact plug-in strip arranges by two ends and with insulator on contact base and the tight pressing of fixed contact on another insulator, the conductive component of this structure, can make the through-current capability of isolating switch greatly improve.
Further arrange, on/off switch operation rotating shaft is set at isolating switch underframe middle part, in operation rotating shaft, be hinged with three operation insulators, the other end and the isolating switch moving contact plug-in strip middle part of operation insulator are hinged, like this, by isolating switch manual-operating mechanism, drive operation rotating shaft to rotate, thereby drive operation insulator move upward and moving contact plug-in strip is pushed out to open position, equally, when needs close a floodgate, by isolating switch manual-operating mechanism, drive operation rotating shaft to rotate to other direction, thereby drive operation insulator move downward and moving contact plug-in strip is pulled to closing position.
Further arrange, in isolating switch underframe one side, earthing switch blade rotating shaft is set and is hinged on the earthing switch blade in rotating shaft, thereby by isolating switch earthing switch blade manual-operating mechanism drive earthing switch blade rotating shaft to rotate to be grounded plug-in strip and isolating switch deciliter so that the high-tension line of isolating switch bottom is overhauled safely.
