Abstract
The utility model provides a switch cabinet with an electric propulsive mechanism, comprising a cabinet body, a high-voltage room and a handcart arranged in the cabinet body, a vacuum breaker that is arranged on the handcart and adjustably is matched with a fixed contact in the high-voltage room and the electric propulsive mechanism matched with the handcart. The electric propulsive mechanism is connected with the handcart through a positioning connecting mechanism of the handcart. The switch cabinet leads the handcart to move between a testing device and a working device through the electric propulsive mechanism so as to realize close and break between the vacuum breaker and the fixed contact. No person is needed to make manual operation on the site. The utility model has excellent electrical performance and small volume and is safe to be used and simple to operate, thereby according with the requirements of miniaturization, automation and high reliability of the switch cabinet by current power grid and being applicable for automatic systems and transformer substations with no person on duty of the power grid.
Description
Technical field
The utility model relates to a kind of switch cubicle, particularly relates to a kind of switch cubicle with electronic propulsive mechanism.
Background technology
At present, its handcart of the switch cubicle that uses moving between test position and service position is manual operation, promptly switch cubicle is provided with handle, using specific purpose tool to drive screw mandrel rotates, thereby make handcart motion, with the fixed contact of realizing being installed in vacuum circuit-breaker moving contact and hyperbaric chamber on the handcart closed with disconnection.Its shortcoming is to be realized at the existing field boundary of operation by the people, can not realize grid automation system and unattended substation.
Summary of the invention
The purpose of this utility model is to provide a kind of can realize handcart moving freely between test position and service position automatically, is adapted to the switch cubicle with electronic propulsive mechanism of grid automation system and unattended substation.
The switch cubicle of the electronic propulsive mechanism of the utility model band comprises cabinet, be arranged on hyperbaric chamber, handcart in the cabinet, be installed on the handcart and with the hyperbaric chamber in the movable vacuum disconnector that cooperates of fixed contact, be arranged on the electronic propulsive mechanism that cabinet is interior and cooperate with handcart.Wherein, electronic propulsive mechanism comprises base, be installed in the motor on the base, electric cabinet that is connected with motor and reducing gear, the shaft coupling that is connected with reducing gear, be connected with shaft coupling and two ends are provided with the leading screw and nut mechanism of bearing pedestal, its two ends are fixed on the slider waveguide rod on the bearing pedestal, the slide block that cooperates with leading screw and nut mechanism and slider waveguide rod, the handcart location coupling mechanism that is arranged on the travel switch collision block on the slide block and cooperates with handcart is arranged on the travel switch mounting panel that has travel switch on the base.For controlling the run location of leading screw and nut mechanism better, realize that the protection feed screw nut is not damaged under the malfunctioning situation of travel switch, leading screw and nut mechanism was provided with the stroke protection mechanism.For avoiding influencing the handcart operation when having a power failure, leading screw and nut mechanism is provided with hand-operated mechanism.Handcart cooperates with track on being installed in base, and is provided with buffer.The hyperbaric chamber is identical with hyperbaric chamber structure in the existing switch cubicle, comprises relay bungalow, secondary cable chamber, hospital bus bar, inlet wire conduit, supporting insulator, fixed contact, current transformer, main bus bar etc.Moving contact on the vacuum circuit-breaker cooperates with the fixed contact in the hyperbaric chamber is movable.
The operation principle of the switch cubicle of the electronic propulsive mechanism of the utility model band is, controller in the operation electric cabinet, make the motor forward or reverse, drive the leading screw and nut mechanism forward or reverse through reducing gear, thereby make the slide block along continuous straight runs left side on it, or move right, by being arranged on handcart location coupling mechanism on the slide block with the handcart dismounting or link to each other, final moving contact and the disconnection of the fixed contact in the hyperbaric chamber and closure that realizes on the vacuum circuit-breaker, the effect of travel switch and travel switch collision block is, in experiment position and service position, travel switch collision block impact stroke switch moving contact, travel switch is disconnected, and then cut off motor and rotate, handcart is advanced or retreat stop motion.
The advantage of the switch cubicle of the electronic propulsive mechanism of the utility model band is because electronic propulsive mechanism has been installed in switch cubicle, can't help the people the existing field boundary realization of operation handcart moving between test position and service position, flexibility and reliability, simple to operate, easy to use, both can carry out local operation, also can carry out a distant place and shake the control operation, meet the requirement of modern power network fully, hold and be not fit to be applied to grid automation system and unattended substation the miniaturization of switch cubicle, automation, high reliability.
