Description
Technical field
The utility model relates to the electric insulation and the technical field that is connected in a kind of gas-insulated switchgear assembly, and specifically a kind of plane rotation of gas insulated metal enclosed swit chgear switch is electrically connected.
Background technology
In the last few years, along with the development of China's electricity market, and the expansion of electricity needs and power station power grid construction scale, the operational reliability of the various high-voltage electrical equipments of electric power system was had higher requirement.At present in the high-voltage appliance switch technical field, air insulation switchgear particularly, generally by circuit breaker, isolating switch, earthed switch, current transformer, voltage transformer, lightning arrester, etc. element form, these elements are independent structures separately, ubiquity that device layout is scattered, floor space is big, install complicated, subsidiary control loop disperses, poor reliability, be difficult to safeguard, particularly the actuating connecting rod of isolating switch and earthed switch is longer, influences the accuracy and the reliability of switch motion.
Summary of the invention
The purpose of this utility model provides that a kind of volume is little, simple and compact for structure, reliability is high, through-current capability is big, and tolerance short circuit current ability is strong, and the plane rotation of gas insulated metal enclosed swit chgear switch applied widely is electrically connected.
The technical solution adopted in the utility model is: a kind of plane rotation of gas insulated metal enclosed swit chgear switch is electrically connected, comprise isolating switch and earthed switch, it is characterized in that: also comprise housing, side in housing is provided with isolating switch, opposite side is provided with earthed switch, the position is provided with rotating shaft between among isolating switch and the earthed switch, rotating shaft one end passes housing and is connected with the operating mechanism of outside, and can under the control of operating mechanism, rotate, the other end of rotating shaft is arranged with the fixed contact seat, this fixed contact seat is a double-plate, rotating shaft between two plates of fixed contact seat is provided with the rotation moving contact, between two plates of fixed contact seat and rotation moving contact, be provided with spring touch finger, described rotation moving contact can be done 360 degree rotations under the drive of rotating shaft, and under the control of operating mechanism, realize three stations, that is: when the rotation moving contact rotated to that side of isolating switch, the position contacted with the fixed contact of isolating switch; When the rotation moving contact rotated to that side of earthed switch, the position contacted with the fixed contact of earthed switch; Rotation moving contact and isolating switch and all discontiguous interposition of earthed switch.
Because the utility model merges the isolation earthing switch that is designed to one three station with isolating switch and earthed switch, and only design has a moving contact, by the rotating shaft driven rotary, realize three station states, little, the simple compact structure of volume not only, and saved the electrical interlock and the mechanical interlocking of isolating switch and earthed switch, and simplified logical relation, make operation more reliable; To rotate moving contact by fixed contact seat and spring touch finger and be connected in rotating shaft, can be under the elastic force effect of spring touch finger, the fixed contact seat is closely contacted with the rotation moving contact, and contact-making surface there is certain contact force, guarantee loaded current, through-current capability is big, improves the short circuit current tolerance, can also guarantee the stable rotation of rotary contact.
