Description

Technical Field

[0001] The utility model relates to the technical field of vacuum circuit breakers, in particular to a new type of vacuum circuit breaker. Background Technique

[0002] A vacuum circuit breaker is a high-voltage electrical equipment that uses vacuum as the arc extinguishing and insulating medium, and is widely used in the power distribution, transmission and control systems of the power system, mainly for cutting off and connecting load current and fault current.

[0003] Many vacuum circuit breaker bodies are installed at high places through mounting brackets, such as on utility poles or electric towers. Due to being at high places, installation, disassembly and maintenance are not very convenient. Generally, a hoisting device is used to hoist and install the vacuum circuit breaker. Multiple workers first fix the mounting bracket on the utility pole or electric tower, and then fix and install the vacuum circuit breaker body and the mounting bracket through a large number of screws. The operation is relatively cumbersome and the screws may become loose during long-term use, resulting in loosening between the vacuum circuit breaker body and the mounting bracket, so there are certain safety hazards. Content of the Utility Model

[0004] The utility model provides a new type of vacuum circuit breaker, which solves the above problems existing in the prior art during use.

[0005] The technical solution of the utility model is realized as follows: A new type of vacuum circuit breaker includes a circuit breaker body and a mounting bracket. The circuit breaker body includes a mechanism box. Mounting seats are integrally formed on both the left and right sides of the mechanism box. Sockets are opened at both the front and rear ends of the mounting seat. A support rod located below the mounting seat is fixedly connected to the mounting bracket. Pad rods are fixedly connected to both the front and rear sides of the mounting bracket with respect to the circuit breaker body. Corresponding sliding openings are opened in each of the pad rods with respect to each of the sockets of each mounting seat. Plug rods are slidably arranged in each of the sliding openings and are used to insert into the sockets. A fixing member for fixing the plug rods is provided on the mounting seat.

[0006] Preferably, each mounting seat is provided with a partition between the sockets at both ends. The fixing member includes a magnetic attraction block fixed on the partition. The plug rod is made of a metal material that can be attracted by the magnetic attraction block.

[0007] Preferably, at least two bayonet openings are opened vertically through the mounting seat. A clamping block is fixedly connected to the support rod. The clamping block is in clearance fit in the bayonet opening. A through hole corresponding to the socket is opened vertically through the clamping block.

[0008] Preferably, a slideway is formed in the side wall of the insertion rod, and the length direction of the slideway is arranged front and back. A limiting block is fixedly connected in the sliding opening of the cushion rod, and the limiting block is slidably matched in the slideway.

[0009] Preferably, a threaded hole corresponding to the position of the slideway is formed in the clamping block, and a screw rod is in threaded fit in the threaded hole.

[0010] Preferably, a connecting hole for inserting the screw rod is formed in the insertion rod.

[0011] Preferably, a resisting plate is fixedly connected to one end of the insertion rod far away from the circuit breaker body, and a handle is fixedly connected to the resisting plate.

[0012] In summary, the beneficial effects of the present utility model are as follows:

[0013] 1. When the circuit breaker body is fixed to the mounting rack, first place the mounting seats on both sides of the mechanism box of the circuit breaker body on the supporting rods on the mounting rack, and then align the insertion openings at the front and rear ends of the mounting seat with the insertion rods on the sliding openings of the mounting seat, insert the insertion rods into the insertion openings and fix them through the fixing parts. This structure is relatively convenient during installation. And after the insertion rods are inserted into the insertion openings and then fixed to the mounting seats through the fixing parts, the circuit breaker body can be firmly fixed on the mounting rack and is not likely to become loose.

[0014] 2. The fixing part is a magnetic attracting block, and the insertion rod is attracted and fixed by the magnetic attracting block, which can reduce the installation steps. As long as the worker inserts the insertion rod into the insertion opening, it can be automatically attracted. As long as the insertion rod does not come out of the insertion opening, the circuit breaker body can be firmly fixed on the mounting rack.

[0015] 3. The mounting seat is provided with a clamping opening, and the clamping block on the supporting rod is fitted in the clamping opening, so that the circuit breaker body can be restricted from sliding in the front and rear directions on the mounting rack. After the insertion rod is inserted into the insertion opening and the through hole of the clamping block, the circuit breaker body can be restricted from sliding in the up and down, left and right directions, so that the circuit breaker body can be more firmly installed on the mounting rack.

[0016] 4. Locking the clamping block and the insertion rod through the screw rod can further improve the connection strength between the circuit breaker body and the mounting rack. BRIEF DESCRIPTION OF THE DRAWINGS
