Abstract
The utility model discloses an indoor high-voltage three-station isolating switch in a power transmission and transformation system. A wall penetrating insulating bottom board 8 is taken as a basic frame of the isolating switch, an insulating contact supporting seat 3 is fixed on the wall penetrating insulating bottom board 8 and a contact 7 is fixed on the insulating contact supporting seat 3. A contacting cutter 6 is fixed on an insulating rotating shaft 1, the insulating rotating shaft 1 is supported on the wall penetrating insulating bottom board 8 via a bearing, the contacting cutter 6 is connected with the conductive part of the wall penetrating insulating bottom board 8 via a flexible connector 4 and a grounding contact 2 and a bus bar 5 are fixed on the wall penetrating insulating bottom board 8. The isolating switch can be used for closing and dividing a switch and grounding on the same switch, and the utility model has the advantages of favorable protective performance, simple adjustment, low loop resistance, compact structure, light weight and reliable insulation performance.
Description
Technical field:
The utility model relates to the indoor high-voltage isolating switch in a kind of power transmission and transformation system, and is relevant with the isolating switch that adopts the insulating material compound inslation especially.
Background technology:
Indoor high-voltage isolating switch is commonly used a kind of for the High-Voltage Electrical Appliances that switch under the high-tension line current-carrying situation and electric equipment such as the high voltage bus circuit breaker that overhauled and charged high-tension line are carried out the electrical equipment isolation of power transmission and transformation system.In the power transmission and transformation system of rated voltage 12kV, three-phase alternating current 50Hz, public is that isolating switch and earthed switch are installed separately at present, and both respectively take charge of its duty, and mechanical interlocking is arranged between the two.This mounting means makes the switch cubicle volume bigger, and the interlock complexity increases complete workload, and operation sequence is loaded down with trivial details.Along with the upgrading of High-Voltage Electrical Appliances original paper, being extensive use of of the particularly appearance of permanent magnetic actuator vacuum circuit breaker, and SF6 on-load switch requires the fixed high-voltage switch cubicle structure compact more, miniaturization more.
Summary of the invention:
The purpose of this utility model is the needs that adapt to the box switch cubicle of compact, designs a kind of miniaturization tri-station isolating switch that isolating switch and earthed switch are combined together.
The technical solution adopted in the utility model is: adopt wall-penetrating type insulating base, insulation rotating shaft, insulation contact bearing and be flexible coupling isolation switch and ground connection disconnecting link are united two into one, isolating switch and earthed switch are combined together, save complexity interlocking between the two, on same switch, realize combined floodgate-separating brake-ground connection.
The indoor high-voltage isolating switch that the utility model provides utilizes the wall bushing structure to realize the locellus of switch cubicle, has improved barrier propterty; Isolating switch and earthed switch are combined together, saved complexity interlocking between the two, guarantee the reliability of switch motion, and adjust simple; Being flexible coupling reduces loop resistance, and temperature rise is lower; Insulation rotating shaft, insulated leg make the construction of switch compactness small and exquisite, weight saving, and the switch cubicle volume-diminished, insulation property are reliable.
Description of drawings:
Fig. 1 is the side figure such as axle of an embodiment of the utility model;
Fig. 2 is the structural representation of the utility model the foregoing description.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure each parts be respectively 1, insulation rotating shaft 2, grounding contact 3, insulation contact bearing 4, be flexible coupling 5, bus-bar 6, contact knife 7, contact 8, wall-penetrating type insulating base
As shown in drawings, wall-penetrating type insulating base 8 is pedestals of isolating switch, insulation contact bearing 3 is fixed on the wall-penetrating type insulating base 8, contact 7 is fixed on the insulation contact bearing 3, contact knife 6 is fixed in the insulation rotating shaft 1, on wall-penetrating type insulating base 8, contact knife 6 connects by 4 current-carrying parts with wall-penetrating type insulating base 8 that are flexible coupling by bearings in insulation rotating shaft 1, and grounding contact 2 and bus-bar 5 are fixed on the wall-penetrating type insulating base 8.When insulation rotating shaft 1 rotation, drive contact knife 6 and rotate together, contact knife 6 from be fixed on contact 7 on the insulation contact bearing 3 and touch fully and separate realization switch separating brake; Insulation rotating shaft 1 continues to rotate to an angle, and contact knife 6 contacts fully with grounding contact 2, realizes switch ground connection.When insulation rotating shaft 1 when the separating brake rightabout rotate, drive contact knife 6 rotates together, contact knife 6 promptly arrives the separating brake position of switch from touching fully and separate with being fixed on grounding contact 2 on the wall-penetrating type insulating base 8; Insulation rotating shaft 1 continues to rotate to an angle, and contact knife 6 contact fully with contact 7 on being fixed on insulation contact bearing 3, realization switch combined floodgate.
