Description
Technical Field
[0001] The invention relates to the technical field of circuit breakers, in particular to an automatic control system and a method for a circuit breaker that does not trip when disconnected. Background Art
[0002] A circuit breaker is a switching device that can close, carry and disconnect current under normal circuit conditions, and can close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague, and those above 3kV are generally called high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. They can automatically cut off the circuit when they have serious overloads or short circuits and undervoltage faults. Their function is equivalent to a combination of fuse switches and over- and under-temperature relays. Moreover, there is generally no need to change components after disconnecting the fault current. At present, it has been widely used.
[0003] Nowadays, when using circuit breakers that do not trip when disconnected, there are the following problems:
[0004] (1) The outer cover is generally fixed to the circuit breaker housing by bolts.

9. A method for implementing the automatic control system of a circuit breaker that does not trip when disconnected according to claim 8, characterized in that: The specific steps include: S1. When it is necessary to open the outer cover (3) to inspect the internal components of the circuit breaker housing (2), the side baffle (9212) is pressed downward by the pressing piece (9213), so that the side baffle (9212) slides along the inside of the hollow plate (9211), thereby losing the limit on the toggle rod (914), and then the toggle rod (914) is rotated backward, and then the slider (91) is pushed forward by the connecting bar (915) and the extension block (916), and then the three folding push rods (92) are driven to move forward at the same time, and then the hook (918) is hung on the hanging ring (919), and the three folding push rods (92) are respectively inserted into three different embedded positioning holes (912), and the three embedded positioning blocks (911) can be respectively pushed out from the three embedded positioning holes (912), and then the outer cover (3) is pulled upward to complete the removal of the outer cover (3); S2. When the circuit breaker housing (2) needs to be removed as a whole, the screw rod (105) is rotated, thereby driving the piston (103) to slide backward along the inner wall of the piston sealing cylinder (102). To ensure the internal air pressure balance of the guide tube (106) and the symmetrical tube (101), the two sealing sheets (107) slide away from each other, thereby driving the two guide positioning rods (108) to move away from each other, so that the two guide positioning rods (108) are simultaneously disengaged from the two insertion holes (109). Then, the circuit breaker housing (2) can be removed from the embedding groove (12), and the circuit breaker housing (2) can be removed as a whole. S3. When the circuit breaker housing (2) needs to be reinstalled, the circuit breaker housing (2) is placed into the embedding groove (12), and then the screw rod (105) is rotated in the opposite direction, thereby driving the piston (103) to slide in the opposite direction, so that the two guide positioning rods (108) are simultaneously inserted into the two insertion holes (109), thereby completing the locking of the circuit breaker housing (2). When the outer cover (3) needs to be installed, the outer cover (3) is directly covered on the outer surface of the circuit breaker housing (2) and pressed, so that the three disks (99) can be respectively inserted into the three hollow positioning cylinders (96), until the three embedded positioning blocks (911) are respectively inserted into the three embedded positioning holes (912) under the elastic action of the elastic sheet (910), thereby completing the installation of the outer cover (3).
10. The method for controlling an automatic control system of a circuit breaker that does not trip when disconnected according to claim 9, wherein the elastic sheet (910) in step S3 is a metal spring sheet.
