The gear wheel is driven by a motor rotation shaft which is controlled by the same PLC electrical control panel to rotate, and the PLC electrical control panel is connected with a remote service unit through a wireless receiving/generating device. According to the interval type liquid control electric knife system, through the mode of hydraulic driving control, a circuit breaker panel and a knife contact head seat can be arranged in a closed environment, the interference of external moisture is prevented, the circuit breaker panel and the knife contact head seat are more safe and reliable, the purpose of remote monitoring is realized at the same time, if an electric shaft is failed, the operation by a manual way can be carried out, and the stability of the operation of the whole system is ensured further.
Description
Technical field
The utility model relates to the electric plug-in strip system of a kind of compartment hydraulic control.
Background technology
In known technical field, the total road of inlet wire of general electrical system opens and closes by knife switch control, knife switch claims again knife switch or isolating switch, it is the simplest in manual electrical equipment and use more a kind of low-voltage electrical apparatus, it is made up of porcelain seat, blade, tool rest and Bakelite Cover etc., be typically used as the switch of insulating power supply, to can safely electric equipment be overhauled or be changed fuse.Tradition knife switch is the pattern of manual control, mainly there is certain potential safety hazard, also there is the structure of controlling by semi-automatic mechanism, but cannot in whole network, form an overall system, be convenient to the people total road of inlet wire that directly docking is registered one's residence from backstage and control.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provide the compartment hydraulic control safe and reliable, that can form integrated control network of a kind of monomer structure electric plug-in strip system.
The utility model solves the technical scheme that its technical problem adopts: the electric plug-in strip system of a kind of compartment hydraulic control, comprise several airtight box bodys, in described airtight box body, be provided with circuit breaker panel and plug-in strip contact headstock, be respectively equipped with initiatively hydraulic cylinder and passive hydraulic cylinder at the outer wall of described airtight box body and the upper surface of plug-in strip contact headstock, and connect by connecting pipe between described active hydraulic cylinder and the bottom of passive hydraulic cylinder, described active hydraulic cylinder stretch out the toothed disc that piston rod is provided with spur rack and is meshed with spur rack, described toothed disc is driven by machine shaft, be provided with the contact head lamellar body being connected by line slide rail with plug-in strip contact headstock in the end of stretching out piston rod of described passive hydraulic cylinder,
Machine shaft in described airtight box body is by its forward rotation of same PLC electrical control panel control or rotate backward, and described PLC electrical control panel is connected with remote service unit by wireless receiving/generator.
Further; in order to protect spur rack; also be convenient in the time that electric rotation shaft breaks down simultaneously; can carry out manual operation; a side part, the whole spur rack that toothed disc described in the utility model is meshed with spur rack is all positioned at places housing, and described placement housing is fixed on the initiatively upper end of the cylinder body of hydraulic cylinder.
Further, consider crashproof buffering, the utility model is provided with anti-collision rubber cushion block at the top of described placement housing.
Further, in order to improve security performance, prevent the generation of electric arc, the utility model is filled with nitrogen in described airtight box body.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design reliable, by the mode of hydraulic-driven control, can make electric rotation shaft drive gear disk, hydraulic pressure between active hydraulic cylinder and passive hydraulic cylinder is changed, thereby play rising or the decline of controlling contact head lamellar body, not only can make like this circuit breaker panel contact with plug-in strip in the environment that headstock can be arranged on sealing, and avoid the interference of extraneous steam, the nitrogen of filling can effectively be avoided the generation of electric arc, more safe and reliable, and traditional electric plug-in strip is for the ease of manual operation, be generally the structural design of exposure formula, can pass through the control to electric rotation shaft simultaneously, realize the object of remote monitoring, if there is electric rotation shaft to break down, people still can operate by the mode of manual handsetting gear dish, further guarantee the stability of whole system operation.
