Description

The through-type three station isolation earthing switch of two ground connection
Technical field
The utility model belongs to the appliance switch field, particularly a kind of pair of through-type three station earthed switches of ground connection.
Background technology
High voltage isolator is a kind of High-Voltage Electrical Appliances that supply line is switched and electric equipment such as the high voltage bus that overhauled, circuit breaker and high voltage supply circuit are isolated commonly used in the electric power system.At present; In the distribution system, most of high pressure is isolated and how earthed switch only is provided with independently two stations, i.e. combined floodgate, two positions of separating brake; And isolating switch and earthed switch are installed separately; Complicated electrical interlock also need be set between the two, make that like this volume of unit switch is bigger, complex structure and increase misoperation probability.Along with the upgrading of switchgear, miniaturization becomes the development trend of switchgear, needs supporting electric equipment structure compactness, miniaturization more more.
The utility model content
The purpose of the utility model provides the through-type three station isolation earthing switch of a kind of a kind of pair of ground connection multi-functional, that structure is small-sized, compact.
To achieve these goals, the utility model is by electric spring operating mechanism, power transmission shaft, high speed grounding switch; Housing, conductor, major loop fixed contact; Disk insulator, three station power transmission shafts, movable contact headstock; Rotary-type disconnecting link, three station ground connection fixed contacts, ground connection dish three-station electric operating mechanism is formed.It is characterized in that: electric spring operating mechanism, high speed grounding switch are mounted on the housing through power transmission shaft.Realize quick grounding function.The major loop fixed contact is installed on the conductor, and rotary-type moving contact is installed on the movable contact headstock, and three station ground connection fixed contacts link to each other with the ground connection dish, through the rotation UNICOM major loop and the grounded circuit of rotary-type moving contact; By conductor, the major loop fixed contact, rotary-type moving contact and movable contact headstock are formed major loop.Movable contact headstock, rotary-type moving contact, three station ground connection fixed contacts, ground connection dish are formed grounded circuit.Drive isolation combined floodgate-separating brake-contact of earth function that three station power transmission shafts are realized switch through the three-station electric operating mechanism.Described electric spring operating mechanism connects high speed grounding switch, and three station power transmission shafts connect with rotary-type moving contact is vertical.Described three-station major loop is the linear pattern water conservancy diversion, has realized isolation, ground connection, and ground connection three functions is integrated fast.
Beneficial effect:
The utlity model has quick ground connection, ground connection and isolation features have miniaturization, and through-type water conservancy diversion is easy to connect, simple in structure, and operational stability is good, the characteristics of long service life.
