Technical field
The present invention relates to transformer safety operation device technical field, more particularly to the transmission operation mechanism of transformer neutral point earth protection device.
Background technology
At present, operation transmission mechanism during the earthing isolator division of general neutral point of main transformer protection device is driven using connecting lever, isolation switch contact needs a horizontal force that moving contact is closed or disconnected in division, and when using connecting lever to be driven, driving torque has horizontal and vertical two components during rotation, with the change of the anglec of rotation, two components are also continually changing, when moving contact division, lucky its horizontal component reaches minimum, when carrying out division in this way, very big strength is needed even to be sometimes difficult to separate, often there is the situation that cannot be separated, therefore the transmission operation mechanism for developing design protection device is needed so as to solve the above problems well.
The content of the invention
It is an object of the invention to provide the transmission operation mechanism of transformer neutral point earth protection device; this operating mechanism easily can carry out switching action to transformer neutral point earth protection device; switching action process is convenient and swift; it is safe and reliable; and labour-saving purpose can be reached; ensure that Contact Breaking/Making Operations are smoothly timely and effective, the advantages of make equipment operation safety coefficient high, good stability.
In order to realize above-mentioned technical characteristic, the object of the present invention is achieved like this：The transmission operation mechanism of transformer neutral point earth protection device, it includes steel bracket, steel bracket top is provided with base, flange base is installed on base, isolation switch insulation is installed on flange base, transmission operation base plate is fixedly mounted on flange base, gear base is installed with transmission operation base plate, travelling gear is installed on gear base, moving contact connecting rod is connected with travelling gear, transmission side plate is arranged on transmission operation base plate, tooth bar constitutes gear drive with travelling gear, the lower end of tooth bar is connected with sliding bar, sliding bar passes through the hole on transmission operation base plate, sliding bar lower end is connected with insulating bar, insulating bar bottom is connected with action bars.
The travelling gear is half gear, can be rotated under the effect of the engaged transmission of tooth bar.
The insulating bar is made of insulating rubber material.
The sliding bar can be slided on transmission operation base plate.
The moving contact connecting rod is engaged the division for realizing disconnecting switch with isolation switch insulation.
The method have the advantages that：
Transmission operation base plate is arranged on flange base first when in use, then travelling gear is arranged on gear base and is fixed on transmission operation base plate, tooth bar is engaged with travelling gear, travelling gear can be just driven around central axis by sliding up and down tooth bar, and then drive the moving contact connecting rod on travelling gear to rotate, turning to certain angle moving contact connecting rod will be in contact with isolation switch insulation, and then connect disconnecting switch, when needs will switch timesharing, only need to by pull joystick, action bars can just drive insulating bar, sliding bar and tooth bar are moved down, the travelling gear being meshed with tooth bar rotates, and then drive moving contact connecting rod to be separated with isolation switch insulation, realize separating for disconnecting switch.
The closure of disconnecting switch can be made using said structure and separate more laborsaving convenient, and improved by the safety coefficient that insulating bar can be operating process, it is ensured that the security of operation.
