Abstract
The invention relates to a high-voltage appliance element, in particular to an isolating switch which can be widely applied to a power transformation and distribution system, particularly to high-voltage switching cabinets and looped network cabinets which have compact structures. The invention aims to provide the isolating switch. Due to an ingenious assembled and modular structural design of a rotary knife arm part, an upper transverse supporting part and a lower transverse supporting part, the structure of the switch is simpler and a phase distance of the switch is adjustable; the switch comprises strutting members, movable knife arms and static contacts, wherein the static contacts are strutted on two sides of the movable knife arms through the strutting members; the movable knife arms correspond to the static contacts one to one; and contact between the movable knife arms and the static contacts is realized through rotation. Due to the unique static contact fixing mode, the mode that the contacts are fixed by adopting insulators in the conventional isolating switch is eliminated; therefore, the isolating switch is more portable and the performance of the isolating switch is more reliable; in a word, the invention aims to provide the isolating switch which has a simple structure, low production and manufacturing cost, light weight, flexibility in and convenience for assembly, debugging and maintenance, small volume and attractive appearance, and is particularly applicable to compact and fixed box-type cabinets and the looped network cabinets; and parts of the isolating switch are high in interchangeability and uniformity.
Description
Technical field
The present invention relates to a kind of High-Voltage Electrical Appliances element, particularly a kind of transformation and distribution system that is widely used in is particularly useful for the high-tension switch cabinet of compact type and the isolating switch in the ring main unit.
Background technology
At present; Isolating switch both domestic and external generally can be divided into disconnecting link formula and rotary two kinds of forms on the structural configuration formula; These two types of isolating switches generally can by base, insulated tension pole and various insulated support, moving knife arm, fixed contact, and the numerous parts of ground connection cutter or the like form; Thereby version is complicated, cost of manufacture is higher, take that volume is big, weight is heavier, install and debugging is relatively poor than trouble, interchangeability and highly versatile, especially be not suitable for being applied in the switch cubicle and ring main unit of compact conformation, can't satisfy the trend and the requirement of distribution equipment miniaturization.
Summary of the invention
The object of the present invention is to provide a kind of isolating switch, the rotating knife arm portion of this switch and go up the lower brace part and make structure simpler through assembly type and modular structural design cleverly is at a distance of adjustable.
Isolating switch of the present invention, it comprises strutting piece, moving knife arm, fixed contact, and in the both sides of moving knife arm, moving knife arm and fixed contact are corresponding one by one through supports support for fixed contact, and the moving knife arm is realized folding through rotation and fixed contact.
The moving knife arm is set to integral structure, and it comprises blade, main shaft, and blade is fixed on the main shaft, and main shaft is made up of joint, and the both sides of blade are provided with joint.
The arranged outside insulating cover of blade, the part that contacts with fixed contact is exposed.
Strutting piece comprises lower brace and support plate, and fixed contact is arranged on the lower brace, and supporting bracket is arranged on the both sides of lower brace, and last lower brace is separately fixed at the two ends of supporting bracket, and main shaft is fixed on the centre of supporting bracket.
Creep distance is set between the fixed contact increases device.
Fixed position between last lower brace and the support plate is adjustable.
The fixed contact fixed form of this uniqueness has been cancelled the mode that traditional isolating switch adopts the insulator fixed contact, makes isolating switch lighter, more reliable performance.In a word, the present invention aim to provide a kind of version simple, manufacture cost lower, in light weight, assemble, debug and keep in repair flexible, advantages of small volume is attractive in appearance, each parts interchangeability and highly versatile, be particularly useful for the isolating switch in fixed box cabinet of compact and the ring main unit.

Embodiment
It comprises strutting piece, moving knife arm, fixed contact isolating switch of the present invention, and in the both sides of moving knife arm, moving knife arm and fixed contact are corresponding one by one through supports support for fixed contact, and the moving knife arm is realized folding through rotation and fixed contact.The moving knife arm is set to integral structure, and it comprises blade, main shaft, and blade is fixed on the main shaft, and main shaft is made up of joint, and the both sides of blade are provided with joint.
The arranged outside insulating cover of blade, the part that contacts with fixed contact is exposed.Strutting piece comprises lower brace and support plate, and fixed contact is arranged on the lower brace, and supporting bracket is arranged on both sides, and main shaft is fixed on the centre of supporting bracket, and last lower brace is fixed on the both sides of supporting bracket.Creep distance is set between the fixed contact increases device.Fixed position between last lower brace and the support plate is adjustable.
With reference to Fig. 1-4, the objective of the invention is to realize like this: isolating switch of the present invention mainly comprises: supporting bracket 1, last lower brace 2, and last lower brace 2 is through being bolted on the supporting bracket 1; Fixed contact 5,7 is upper and lower to be fixed on the Reinforced Nylon rod through bolt; Binding post as upper and lower port; Then the pyrocondensation creep distance being increased device 8 also is contained on the Reinforced Nylon rod; Play the effect that increases creepage distance; The fixed contact fixed form of this uniqueness; Cancelled the transmission isolating switch and done the way that fixed contact supports with insulator, made more compact structure, quality is lighter; Moving knife arm 6 adopts the integrated module structure, compares with link insulator with existing steel axle of isolating, and compact conformation, simple, at a distance of adjustable.The moving knife arm portion is installed in to be installed on the supporting bracket 1, can rotate freely, and can realize the separating brake and the closing function of isolating switch during operation deciliter end axle; The moving knife arm portion is made up of both sides joint 10, insulating cover 11, middle joint 12, blade 13, a deciliter end axle 14 again, and joint generally is made up of insulating material such as epoxy resin, lighter weight; Be connected through bolt between joint and the joint; Before the assembling joint, blade and insulating cover are contained in the space between joint; Adopt this mode of insulating cover that blade is wrapped up, effectively guaranteed this isolating switch to safe distance requirement, make the isolating switch compact overall structure.Simultaneously, parts such as joint, blade and insulating cover all can be realized standardization, General design and production, and simple and reliable for structure, cost is lower, assembles and keep in repair flexible.
