Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a portable universal quick-install circuit breaker emergency release structure. Background Art

[0002] 10kV vacuum circuit breakers are not allowed to be operated manually or on-site. For the on-site opening and closing of 10kV circuit breakers, the operation must be delayed until the power is cut off at the upper level. At present, in China, once the 10kV circuit breaker cannot be opened and closed, the upper level power outage is usually adopted to solve this problem. However, due to the normal operation of the mechanism and the line, this measure will not only affect a single line, but also more than a dozen other lines on the entire busbar. This leads to a serious reduction in power supply reliability. There are many types of circuit breaker opening buttons, and the surrounding adsorption surfaces are also made of various materials. The current solution cannot fully adapt to a variety of buttons or cabinets. The most representative way of device adsorption cabinet surface is the strong magnetic base. When the power switch is turned on, there is magnetism, and when it is turned off, there is no magnetism. However, in this method, the magnetic base has a large power supply and needs to be equipped with a large-capacity battery, which is inconvenient to use on site. Utility Model Content

[0026] Reference Figures 1 to 4 The utility model provides a portable universal quick-install circuit breaker emergency release structure, and makes the following embodiments:

[0027] In some embodiments, a portable universal quick-install circuit breaker emergency release structure includes a pushing component, a rotating component and a detachable bracket 300, and the detachable bracket 300 is used to fix the pushing component and the rotating component to fix the emergency release structure relative to the disconnect switch.

[0028] The pushing component includes a driving module 100 and a push rod 110. The driving module 100 includes a driving shell, in which a driving unit 120 is arranged. The driving unit 120 can be a motor. The driving unit 120 can drive the push rod to move up and down relative to the driving shell. The driving shell is also provided with a main control module, a data receiving module, etc. The wireless remote control sends a signal instruction, the data receiving module receives the instruction, and inputs it into the main control module. The main control module decodes the signal and operates the driving unit 120 according to the decoded content, thereby realizing the push rod opening.

[0029] The data receiving module is mainly used to receive the signal data sent by the wireless remote control; the main control module is mainly used to control the operation of each component of the device, and performs corresponding control operations on the equipment by receiving and processing the signals from the data sending module; the driving module 100 is mainly used to receive instructions from the main control module to realize the push rod opening.

[0030] There are three types of existing opening switches: push-type, rotary type, and rotary push-type. In order to improve the availability of the equipment, a rotating assembly is designed for the rotary opening switch, which includes a rotating module 200, a rotating base, and a rotating chuck 210. The rotating module 200 is arranged at the lower end of the drive housing. The rotating module 200 includes a rotating drive unit 120 and a rotating chuck 210. The rotating drive unit 120 drives the rotating chuck 210 to rotate. The rotating chuck 210 is provided with a rotating hole 211. The push rod 110 extends from the middle of the rotating chuck 210. The rotation of the rotating chuck 210 and the movement of the push rod do not interfere with each other, and the two can move separately.

[0031] The rotating base is realized by the rotating drive unit 120, which can be a rotating motor. The rotation of the rotating motor is transmitted to the rotating chuck 210 through gear transmission. The rotating chuck 210 can rotate, and the rotating motor drives the gear transmission, so that the rotating chuck 210 can rotate at a stable speed. In order to realize the forward and reverse rotation of the rotating motor, a commutator is used to change the direction of the motor by changing the direction of the current. When the direction of the current is consistent with the direction of the rotation of the rotating motor, the rotating motor rotates forward; when the direction of the current is opposite to the direction of the rotation of the rotating motor, the rotating motor reverses. Each time the wireless remote control is operated, it rotates 90° in the corresponding direction. At the same time, the rotation adaptive technology is adopted. When the rotating motor drives the gear to rotate to a certain limit, that is, the switch has been rotated within 90° and cannot rotate anymore. After 3 seconds, the device completes the command operation.

The rotating chuck 210 is provided with a plurality of blocks 212 arranged in an annular interval, and the blocks 212 are provided with a bayonet slot. When rotating, the bayonet slot can be engaged with the opening switch, which is convenient for driving the opening switch to rotate.

[0033] The detachable base 320 is provided with a slot 321, and a screw rod 322 is provided through the lower clamping surface of the slot 321, a pressing block is fixedly installed at one end of the screw rod 322, and an adjustment handle 333 is fixedly installed at the other end of the screw rod 322. The adjustment handle 333 is convenient for rotating the screw rod 322.

[0034] The pressing block is provided with a plurality of switching holes 334, which are threadedly connected to the screw rod 322. The upper clamping surface and the nail surface use a large area grid rubber pad to improve the anti-slip performance of the plane clamp. The lower clamping surface can switch the hole 334 to adapt to various situations.

[0035] A detachable bracket 300 is provided to fix the emergency trip structure so that the pushing component and the rotating component are near the opening switch, wherein the push rod 110 presses the opening switch, and the rotating chuck 210 rotates the opening switch. The push rod 110 and the rotating chuck 210 can press and rotate the opening switch at the same time, and a driving unit 120 and a rotating unit are provided, so that the three types of opening switches of the push type, the rotating type, and the rotating push type can be remotely tripped respectively.
