Description
The application is Application No. 201510035803.5, and the applying date is on January 23rd, 2015, and invention and created name is
The divisional application of the application for a patent for invention of " specific purpose tool changed by switch touching thrum spring ".
Technical field
The present invention relates to electric power system maintenance changes Work tool field and in particular to one kind gw4 type be applied to power system
The specific purpose tool that outdoor disconnector fingertip spring is changed.
Background technology
Disconnecting switch is one of most widely used electrical equipment in power system, plays a part conductive and isolation, right
Power network safety operation is most important.Disconnecting switch species and model are more, and wherein gw4 type outdoor disconnector is conductive because of it
Relatively simple for structure obtain relatively broad application.Gw4 type outdoor disconnector is mainly made up of moving contact and static contact, its
Moving contact is typically made up of each 3 contact finger pieces in left and right, 3 springs, spring pin and c type metallic plate；Spring, spring pin and c
Type metallic plate jointly contact finger piece is fixed on conductive arm, and provides certain elastic force so that contact finger piece is clamped.Subsequently connect with static contact
Connect, constitute galvanic circle.
In fingertip spring use environment severe out of doors, easily produce serious corrosion so that the elasticity of spring subtracts
Weak, the phenomenon of spring breakage even can occur so that disconnecting switch performance impairment or damage completely when serious, the serious danger side of body is to supplying
The safety of electricity.Thus, the state of regular check fingertip spring, in time the fingertip spring of corrosion is changed, to guarantee to isolate
Switch runs healthy and stablely and seems very necessary.Gw4 type outdoor disconnector changes fingertip spring at present, due to lacking effectively
Specialist tools, the dismounting of fingertip spring and change installation rely primarily on maintainer using the simple tools such as hammer free-hand enter
OK, maintainer is after assembling contact finger piece, spring, spring pin and c type metallic plate, and free-hand pressing contact finger piece overcomes elastic force
Make spring elongation, conductive arm is installed after enlarged openings, this process needs very big strength, is accidentally easy for hurting handss
Refer to.Simultaneously because during free-hand pressing, c type metallic plate meeting angular displacements, lead on screw and conductive arm on c type metallic plate
Screw cannot align, and needs to be beaten with hammer, and it is injured in operation process to be not only easily caused maintainer, also can damage fingertip
Silver coating, so that contact finger piece is damaged, affect its service life, reduce operational reliability.And, traditional work method needs 2
The personnel's cooperation having certain maintenance experience completes, and takes longer.
