Abstract
The invention discloses a rapid grounding switch, which solves the problems in the prior art that the breaking speed between grounding fractures of a rapid grounding switch is slow, an effect of rapidly breaking induced current is difficult to realize, and the ace burning is uneasy to put out, SF6 gas with a good insulating property must be taken as insulating gas in the prior art for achieving the purpose of rapidly breaking induced currents, thereby causing environmental pollution. The rapid grounding switch disclosed by the invention is characterized in that a moving conductor is arranged in a cavity of a grounding conductor, a conductive tube is installed in the cavity of an insulating conductor, a breaking spring and a conducting rod are arranged in the cavity of the moving conductor, and a sliding shaft arranged on the moving conductor can slide in a U-shaped groove arranged at the front end of a driving arm. The rapid grounding switch disclosed by the invention has the advantages that because the breaking spring is taken as a dynamic force pf the rapid breaking of the grounding switch, and through the rapid breaking of the conducting rod and the generation of compressed air blowing, an effect of instant arc extinguishing between the grounding fractures is achieved, so that the rapid breaking of the grounding switch is realized, therefore, clean dry air or nitrogen gas can be adopted as insulating gas, therefore equipment becomes more environmentally-friendly.
Description
Technical field
The invention belongs to the high-tension electricity technical field, the insulated metal sealing switch equipment that particularly is used for clean dry air or nitrogen has the pass and closes short circuit current and cut-off a kind of high speed grounding switch of induced current ability.
Background technology
High speed grounding switch is the important electric elements on the fixed switchgear, can realize the quick ground connection of bus or cable, and the safety device during as protection and maintenance plays important effect in whole electric power system.In the prior art; Be 200720064391.9 and be called the disclosed high speed grounding switch of patent of " high speed grounding switch that is used for High-Voltage Electrical Appliances " like application number; First connecting plate that the technical scheme that adopts is a movable contact rod through hinge links to each other with the power transmission shaft of joining electric spring operation machine outward with second connecting plate; Power transmission shaft by external electric spring operation machine rotates drive movable contact rod linear reciprocating motion, is grounded cut-offfing with the pass of switch and closes.The speed of cut-offfing of said structure movable contact rod is that the power transmission shaft of electric spring operation machine provides; Because the power transmission shaft of intermediate demand operating mechanism is through the transmission of second connecting plate and first connecting plate; So the speed of cut-offfing between the ground connection fracture is still slower; If when therefore between the ground connection fracture, filling with dry air or nitrogen; Cut-off very difficulty of induced current; Arcing is difficult for extinguishing; For realizing the faradic purpose of quick-speed turning on-off; Prior art has only the good SF6 gas of the insulating capacity of use as insulating gas, can cause environmental pollution like this.
Summary of the invention
Technical problem to be solved of the present invention is; Overcome the weak point of prior art, provide a kind of insulated metal sealing switch equipment that is used for clean dry air or nitrogen to have the pass and close short circuit current and cut-off a kind of high speed grounding switch of induced current ability.
The technical scheme that the present invention adopts comprises insulated conductor, earthing conductor and moving-conductor; Be separately installed with main fingertip spring at the inner chamber of insulated conductor and the inner chamber of earthing conductor; In the inner chamber of insulated conductor, contact tube is installed; Disjunction fingertip spring is installed in the inner chamber of contact tube; Said moving-conductor places the inner chamber of earthing conductor; Spring and conducting rod are installed in the inner chamber of moving-conductor; Sliding axle is installed on moving-conductor; Actuating arm is installed in protective cover, and said actuating arm front end is processed with U type groove.
The front end of said conducting rod is processed with the bulb with the body of rod rounding off of conducting rod.
What the front end of said insulated conductor and the front end of earthing conductor all had a charged field shield effect seamlessly transits the curved surface head.
The invention has the beneficial effects as follows; Cut-off the power of spring owing to adopt as the quick disjunction of earthed switch; Through conducting rod cut-off rapidly and produce the compression air-blowing; Play the effect of between ground connection fracture moment arc extinguishing, realized cut-offfing rapidly of earthed switch, thereby can use clean dry air or nitrogen as insulating gas; Need not use SF6 gas as insulating gas; Make more environmental protection of equipment, simultaneously, the present invention also can be grounded switch and close the ability of closing short circuit current.

Embodiment
As shown in drawings; The present invention includes insulated conductor 2, earth conductor 10 and moving-conductor 7; Be separately installed with main fingertip spring 4 at the inner chamber of insulated conductor 2 and the inner chamber of earth conductor 10; Contact tube 1 is installed in the inner chamber of insulated conductor 2; Disjunction fingertip spring 3 is installed in the inner chamber of contact tube 1; Said moving-conductor 7 places the inner chamber of earth conductor 10; Spring 6 and conducting rod 5 are installed in the inner chamber of moving-conductor 7; Sliding axle 11 is installed on moving-conductor 7; Actuating arm 8 is installed in protective cover 9; Said actuating arm 8 front ends are processed with U type groove; Sliding axle 11 is installed on the moving-conductor 7 can slide in the U type groove of actuating arm 8 front ends processing, and what the front end of the front end of said insulated conductor 2 and earth conductor 10 all had a charged field shield effect seamlessly transits the curved surface head.
During use; Said insulated conductor 2 and bus mechanical connection; Earthing conductor 10 is connected through mechanical seal with the metal shell of switchgear; Protective cover 9 is installed on the housing of switchgear; Under the diagram conducting state; Moving conductive body 7 one ends are realized being electrically connected through main fingertip spring 4 and insulated conductor 2, and moving conductive body 7 other ends are realized being electrically connected through main fingertip spring 4 and earthing conductor 10, in the disjunction fingertip spring 3 that conducting rod 5 inserts on the contact tube 1.When the drive arm 8 is quickly driven cutter actuator 12 is rotated around the shaft, moving conductor 7 shaft 11 is driven by a sliding arm 8 ground conductor 10 can be driven in reciprocation of the knife switch to achieve fast closing and opening break;? moving conductor 7 under the action of the drive arm 8 breaking exercise, because breaking fingers clamping force of the spring 3, conductive rod 5 no immediate pull out, when the moving conductor 7 running into the distance isolated conductor 2? certain distance, the conductive rod 5 6 under the action of the spring to overcome the conductive tube 1 of the finger breaking the clamping force of the spring 3, the conductor 2 and isolation finger breaking quickly disengaged spring 3, the purpose of breaking up the moment, Meanwhile, the movable conductor 7 of the gas chamber 5 by the conductive rod instantaneously discharged compressed to form a compressed air blow, play fast fracture between the ground interrupter role in breaking induced current, therefore the present invention can be used in clean dry air or nitrogen as an insulating metal-enclosed gas-insulated switchgear apparatus, the distal end of said conductive rod 5 machining a smooth transition to the conductive body of legs ball head, in the on-state and off of the ball spring 3 is in contact with the fingers to ensure that the breaking of finger spring 3 has a certain clamping force, only when the conductive rod breaking the fingers 5 to overcome the clamping force of the spring 3 can be quickly disconnected.
