Embodiment Construction

[0024] Accompanying drawing is the specific embodiment of the present invention. Such as Figure 1 to Figure 8 As shown, this kind of automatic opening and closing high-voltage drop circuit breaker includes an installation base 1, an insulating magnet 2 and a ring tube 3 are installed on the installation base 1, a static contact 4 and a static inclined surface 5 are installed on the insulating magnet 2, and the ring tube Install movable contact 6 on 3, and movable contact 6 is also inclined-plane structure, and after movable contact 6 contacts with static inclined surface 5, locks movable contact 6, and simultaneously movable contact 6 contacts with static contact 4 and connects circuit.

[0025] An electromagnet 7 is installed at the bottom of the ring tube 3, the telescopic rod of the electromagnet 7 is connected to a pull rod 8, and the upper end of the pull rod 8 is connected to a sleeve 9 with the opening facing downward, and the sleeve 9 is set on the top of the ring tub...

Abstract

The invention relates to the field of power supply facilities, and particularly discloses an automatic opening and closing high-voltage drop circuit breaker. It drives the transmission gear through the motor, and the transmission gear and the toggle lever respectively drive the transmission wheel to move left and right and rotate through the transmission parts; the rotation of the screw makes the first pawl and the second pawl move downward, and the second return spring is squeezed , after the first pawl is separated from the first pawl, the accumulated force is released, and the guide rod moves upwards quickly, and the gram tube is driven to rotate through the guide post and the rotating rod to realize closing; after the electromagnet is energized, the telescopic When the rod is retracted, the pull rod drives the sleeve downward, so that the moving contact is separated from the static contact, and the gram tube falls to realize the brake breaking. The invention uses manual or remote control to control the forward and reverse motors and electromagnets, so as to achieve the purpose of opening and closing through a series of mechanical actions, avoiding the inconvenience caused by excessive fuses and uneven terrain, and also avoiding rainy days. unsafe factors.

Description

technical field [0001] The invention relates to the field of power supply facilities, in particular to an automatic opening and closing high-voltage drop circuit breaker. Background technique [0002] Most of the transformers provided to users in our country use 10KV power supply lines for power supply facilities, and a drop-out circuit breaker that can stop the input high-voltage line power supply is installed on the transformer. This equipment has a simple structure, low cost, and is easy to use and install. Some unsatisfactory places, such as the height of the installation, make it difficult for the power transmission staff to hold the Lingke rod in place accurately. At night and in rainy days, it is difficult to complete the power outage and transmission work, and there are also great potential safety hazards. There are piles of sundries underneath, and the uneven terrain also brings a lot of trouble to the staff. During the operation, sometimes due to different angles...
