Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to a protection tripping control system and method for an embedded circuit breaker. Background Art

[0002] Embedded circuit breakers are mainly used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. They can automatically cut off the circuit when serious overloads, short circuits, undervoltages, and other faults occur. Their function is equivalent to a combination of a fuse-type switch and an over- and under-temperature relay.

[0003] When a short circuit or overload occurs in the circuit and causes the circuit breaker to trip, the movable end plate inside is usually driven by the trip unit to reverse quickly and separate from the static end plate to disconnect the circuit. Due to the lack of protection during tripping, the movable end plate produces a large impact and noise when tripping. Since the tripping parts are usually made of plastic insulating material, the end connection of the movable end plate is prone to breakage. In addition, excessive impact force can easily cause the movable end plate to rebound, reducing the use effect of the equipment. Summary of the Invention

[0006] Preferably, several of the elastic ribs are installed at an angle, and the installation positions correspond to the protective components. Several of the elastic ribs are fixedly installed inside the body through the cooperation of the arc plates on both sides and the fixing frame.

[0007] Preferably, the protective component includes a limiting sleeve, which is fixedly installed inside the machine body and has an iron core column slidably installed on the end. A coil is wound around the outside of the limiting sleeve. A transmission part and a transmission plate are rotatably installed inside the machine body. A movable end plate is fixedly installed on the outside of the transmission part. A rubber ring is fixedly installed inside the movable end plate, and one end of the iron core column is inserted into the interior of the rubber ring. The installation position of the movable end plate corresponds to the installation position of the static end plate and several elastic ribs.

[0008] Preferably, the protective component also includes a conductive sheet, which is fixedly installed inside the body and the installation position is located at the bottom of the transmission plate. One end of the conductive sheet is connected to the end of the second terminal, and a wire is provided between the other end of the conductive sheet and the coil, and a soft connection is achieved through the wire.

[0009] Preferably, a wire is provided between one end of the movable end plate and one end of the coil, and a flexible connection is achieved through the wire. The other end of the movable end plate is set as an inclined surface, and the included angle is 70°.

[0010] Preferably, a rectangular ring frame is fixedly mounted on the inner side of the switch member, and the other side of the rectangular ring frame is rotatably connected to one side of the transmission member.

[0011] Preferably, the positioning assembly includes an assembly plate, and positioning grooves and limiting slide grooves are symmetrically opened on both sides of the interior of the assembly plate, and positioning blocks are slidably installed inside the limiting slide grooves on both sides.

[0012] Preferably, the positioning blocks on both sides are fixedly mounted on both ends of the side of the machine body, and the positioning blocks on both sides are parallel to each other.

[0013] The present invention also discloses a control method for a protection trip control system of an embedded circuit breaker, which specifically includes the following steps:

[0014] S1. Circuit connection: First, connect the machine body to the circuit that needs to be protected. During the connection process, connect the wires to terminal 1 and terminal 2 respectively. Then fix the machine body to the wall surface or control box. During assembly, first use bolts to install the assembly plate through the positioning slot to the preset position, and then insert the machine body into the corresponding limit slide slot through the positioning block to complete the assembly of the machine body;

[0015] S2, circuit protection, first push the switch piece so that its rectangular ring frame pushes the transmission piece to run, so that it drives the moving end plate installed on the side to fit with the static end plate, completing the circuit connection. The current passes through terminal 1 and the static end plate and then reaches the moving end plate, and then reaches the coil through the flexible connection, and then reaches the conductive sheet through the flexible connection at the other end of the coil, and then reaches terminal 2. When a short circuit occurs in the circuit, the coil will instantly generate a large current. Through the principle of electromagnetism, the coil will generate suction to move the iron core column downward, driving the moving end plate downward and separating from the static end plate. At the same time, the switch piece can be returned to its original position through the transmission piece. When the circuit is overloaded, the conductive sheet will be heated and bent upward to push up the transmission plate, so that the transmission plate pushes the transmission piece to separate the moving end plate from the static end plate, thereby achieving circuit protection;

[0016] S3, tripping protection. When the transmission part drives the moving end plate to disconnect at the moment, it will move downward quickly through the tripping mechanism. Through the setting of the protection component, the quickly disconnected moving end plate can hit the surface of the elastic rib, causing the elastic rib to deform. At the same time, the pressure plate can always fit with the moving end plate through the cooperation of the spring body. When the moving end plate is disconnected, the pressure plate can drive the positioning column installed on the end slidingly to slide inside the arc-shaped positioning frame as the moving end plate rotates. After the moving end plate rotates to the maximum angle, the inner sliding rod installed on the end of the positioning column slides to the position of the positioning hole, and then is pushed out and inserted into the positioning hole by the cooperation of the support spring, completing the protection and limitation of the moving end plate. When the circuit is reconnected, it is only necessary to pull the elastic pull rope outward through the pull ring, so that the positioning column drives the inner sliding rod to disengage from the positioning hole, and the circuit can be reconnected by rotating the switch.

[0017] Preferably, the arc extinguishing device is used to isolate the arc generated when the circuit is disconnected or connected, thereby achieving the effect of timely disconnection and safety protection.

When the movable end plate is disconnected, the pressure plate can rotate with the movable end plate while driving the positioning column installed on the end slidingly to slide inside the arc positioning frame until the movable end plate rotates to the maximum angle, and the inner sliding rod installed on the end of the positioning column slides to the position of the positioning hole, and then is pushed out and inserted into the positioning hole by the cooperation of the support spring, completing the protection and limiting of the movable end plate, improving the protection effect of the transmission part and the movable end plate, and at the same time, by positioning the movable end plate, the rebound phenomenon can be effectively avoided, thereby improving the use effect of the equipment.

[0036] The embodiment of the present invention further discloses a control method for a protection trip control system of an embedded circuit breaker, which specifically includes the following steps:

[0037] S1. Circuit connection: First, connect the body 1 to the circuit to be protected. During the connection process, connect the wires to the terminal 1 101 and the terminal 2 102 respectively. Then, fix the body 1 to the wall surface or the control box. During assembly, first use bolts to install the assembly plate 6 through the positioning slot 601 to the preset position, and then insert the body 1 into the corresponding limiting slide slot 602 through the positioning block 603 to complete the assembly of the body 1;

[0038] S2, circuit protection, first push the switch member 3 so that its rectangular ring frame 301 pushes the transmission member 5 to operate, so that it drives the movable end plate 501 installed on the side to fit with the static end plate 1011, completing the circuit connection, and the current reaches the movable end plate 501 after passing through the terminal 1 101 and the static end plate 1011, and then reaches the coil 801 through the flexible connection, and then reaches the conductive sheet 7 through the flexible connection at the other end of the coil 801, and then reaches the terminal 2 102. When the circuit is short-circuited, the coil will instantly generate a large current. Through the principle of electromagnetism, the coil 801 will generate suction to move the iron core column 802 downward, driving the movable end plate 501 downward and separating from the static end plate 1011. At the same time, the switch member 3 can be returned to its initial position through the transmission member 5.

The positioning frame 15 slides inside until the movable end plate 501 rotates to the maximum angle, and the inner slide rod 1402 slidably installed at the end of the positioning column 14 moves to the position of the positioning hole 1502, and is then pushed out and inserted into the positioning hole 1502 by the cooperation of the support spring 1403, completing the protection and limitation of the movable end plate 501.
