technical field

The invention relates to the technical field of high-voltage fuses, in particular to a 35kV high-altitude high-voltage fuse sleeve-type fuse grabbing device.

Background technique

A fuse refers to an electrical appliance that fuses the melt with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is a current protector made by using the heat generated by itself to melt the melt after the current exceeds the specified value for a period of time, thereby disconnecting the circuit. Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As a short circuit and overcurrent protector, it is one of the most commonly used protection devices.

High-voltage fuses have been widely popularized and applied in the power industry due to their safety, reliability and economy. At present, most substations use voltage transformers of 35kV and below for protection by high-voltage fuses. When the high-voltage fuse is blown due to voltage fluctuation or other reasons, the fuse in the fuse must be replaced in time to ensure the safe and stable operation of the power grid.

However, the installation position of the fuse is relatively high. For example, the position of the 35kV outdoor fuse is generally 4-6 meters above the ground. At this stage, to replace the fuse, an insulating ladder of more than 4 meters is required. The operator climbs to a height of 4-6 meters to replace the fuse. When the personnel work at high altitude, a special escalator is required to go up and down the ladder. At this stage, not every substation has it. Long enough insulation ladders require pickup trucks or small trucks. It is very inconvenient to transport the insulation ladders, and the replacement time after the fuse is blown cannot be guaranteed, which is inefficient and affects production. At the same time, there are certain safety hazards for operators working at high altitudes.

CN107706796A discloses a holder for replacing fuses, which is characterized in that it comprises a body, a clamping mechanism is arranged on the upper end of the body, a driving mechanism is placed in the body and fixedly connected, a handle is placed on the bottom surface of the body and Solid connection. The method of use is: first adjust the right clamping plate to the maximum stroke, then adjust the left clamping plate and the left guide rail to the appropriate position, and place the fuse between the left clamping plate and the right clamping plate, and the left end cover. It is located in the U-shaped groove of the left clamping plate, starts the motor reducer, drives the driving mechanism to rotate, and drives the screw to rotate at the same time, and drives the fixed right clamping plate to move to the left, and the left clamping plate and the right clamping plate are clamped. Tighten the left and right end covers of the fuse, the motor reducer stops moving, manually remove the bolts on the end covers, and then start the motor reducer to reversely rotate, so that the right clamping plate moves in the reverse direction, and the spring inside the fuse is loosened After that, remove the end cap, and then remove the product to replace the fuse.

Specifically, FIG. 1 shows a schematic structural diagram of the sleeve-type self-locking end cover of the 35kV high-altitude high-voltage fuse, and this state is also the state of the self-locking end cover during normal operation. As shown in FIG. 1 , the casing base 1 is a cylinder with a through hole in it, the diameter of the through hole is about 55mm, and the through hole is formed as an accommodating portion, and the accommodating portion is configured to accommodate a safety tube, which is not shown in the drawings of this embodiment. Wherein, the fuse can be a fuse in the prior art, one end of which is fixed to the sleeve base 1 , and the other end is in contact with the movable cover 5 by the elastic force exerted by the first elastic member 2 .

The movable cover 5 is movably connected with the sleeve base 1; the movable cover 5 is provided with a movable cover protruding end 51, the movable cover 5 is in an "L" shape, and the movable cover protruding end 51 is provided with a movable cover Operation hole 4; the movable cover 5 can be turned or slid relative to the sleeve base 1 to form the opening and closing of the accommodating portion; The sleeve bases 1 are connected through hinges, and the movable cover 5 can be turned over relative to the sleeve base 1 to constitute the opening and closing of the accommodating portion. But it is not limited to this, as long as it is convenient to operate the operation hole 4 of the movable cover and constitute the opening and closing of the accommodating portion.

The locking portion is configured to lock the movable cover 5 to close the accommodating portion. In one specific implementation of this embodiment, the locking portion includes a first elastic member 2 and a latch 3 . Specifically, the first elastic member 2, which is fixedly connected under the casing base 1, is configured to be compressed when the accommodating portion is closed, and can be released due to its own elastic recovery when the accommodating portion is opened. Activate pin 3 to reset. The plug 3 is fixedly connected to the first elastic member 2, the plug 3 is provided with a protruding end 8, the plug 3 is in an “L” shape, and the plug protruding end 88 is configured so that when the accommodating portion is closed The locking of the movable cover 5 is configured to lock the movable cover 5 when the accommodating portion is closed. As shown in FIG. 1 , the movable cover 5 is caught by the latch 3 .

The unlocking portion is provided with an unlocking operation portion, and is configured to accept an external unlocking operation to unlock the movable cover 5 . In another specific implementation of this embodiment, the unlocking operation portion can be driven by an external force to drive the latch 3 to move down, so as to release the latch 3 from blocking the movable cover 5 . Specifically, in this embodiment, the unlocking operation portion is provided at the end of the latch 3 away from the first elastic member 2 , and the unlocking operation portion is a pull ring 6 . By applying a downward force to the pull ring 6, the blocking of the movable cover 5 by the latch 3 can be released, and the movable cover 5 can be opened for the next step of replacing the fuse.
