Abstract
The utility model discloses a vertical contact grounding switch. A grounding switch blade (4), a grounding connecting lever (1) and a V-type rotating shaft (5) are fixed together to form a grounding switch assembly which is arranged on a pedestal (2). A mounting surface of each of contacts (3) is perpendicular to a mounting surface of the pedestal (2). The grounding switch has a small size, allows air insulating distances among the contacts to be wide, is flexible and practical, and is safe and reliable.
Description
Technical field
The utility model relates to a kind of earthed switch.
Background technology
Need to use earthed switch in multiple electric power system, manufacture of intraocular ground connection when overhauling as high-voltage electrical equipment is exempted from Danger Electric shock risk to guarantee the maintainer.Existing earthed switch mostly is the contact installed surface and is parallel to underframe installed surface structure, consisted of by underframe, ground connection blade, earthed crank arm, V-type rotating shaft, post insulator and contact, post insulator is contained on the underframe, contact is contained on the insulator, be fixed together the earthing erection that forms on underframe by ground connection blade, earthed crank arm, V-type rotating shaft, rotarily drive earthing assembling by manual operation V-type axle, be grounded blade and contact deciliter.The earthed switch contact is wide, and for satisfying the air insulation requirement, phase spacing requires large, and it is many to take up room.
The utility model content
The purpose of this utility model is a kind of vertical contact earthed switch of design.
The technical solution of the utility model is: a kind of vertical contact earthed switch, comprise underframe, ground connection blade, earthed crank arm, V-type rotating shaft and contact, it is characterized in that, be fixed together the earthing erection that forms on underframe by ground connection blade, earthed crank arm, V-type rotating shaft, the contact installed surface is perpendicular to the underframe installed surface, rotarily drive the earthing assembling by operation V-type axle, be grounded blade and contact deciliter.
The vertical contact earthed switch structure that the utility model provides on original Integral earthing switch basis, has changed the direction of contact installed surface, has increased the air insulation distance between adjacent contact, satisfies earthed switch security reliability, versatility requirement.Rational in infrastructure, volume is little, makes simple, easy for installation, applied widely.
