    摘要: The present invention discloses a thermal adjustable tripping device for a miniature circuit breaker, which is mounted in a base (101) of the miniature circuit breaker. The thermal adjustable tripping device comprises: a tripping mechanism (106), a thermal deformation element (107) and an adjusting mechanism (102). The tripping mechanism is provided with an extending tripping rod (161). The thermal deformation element is arranged close to the tripping rod and a gap is reserved between the thermal deformation element and the tripping rod. The adjustment mechanism adjusts a distance of the gap between the tripping rod and the thermal deformation element. A current in a loop accessed by the miniature circuit breaker enables the thermal deformation element to generate heat and deform, and the deformed thermal deformation element moves towards the tripping rod, contacts with the tripping rod and pushes the tripping rod to trigger the tripping mechanism to trip. The adjusting mechanism adjusts the distance between the thermal deformation element and the tripping rod so as to adjust a setting current in the loop. The present invention uses a rigid element to adjust a distance between a thermal deformation element and a tripping rod, which can ensure that the distance between the thermal deformation element and the tripping rod is constant in each operation. The tripping device of the present invention is applicable to an electric motor.

    摘要: An electrical path for a circuit breaker, comprising: an inlet contact group (121, 122); an outlet contact group (131, 132); and a conductive assembly (115, 111, 112). The inlet contact group (121, 122) is connected to an inlet terminal (123), and the outlet contact group (131, 132) is connected to an outlet terminal (133). The conductive assembly (115, 111, 112) comprises a soft connection assembly (115) and a hard connection assembly (111, 112). The hard connection assembly (111, 112) is fixed to a base of the circuit breaker; the soft connection assembly (115) is connected to the inlet contact group (121, 122) and the outlet contact group (131, 132); the soft connection assembly (115) and the hard connection assembly (111, 112) are connected to provide an electrical path between the inlet contact group (121, 122) and the outlet contact group (131, 132). The inlet contact group (121, 122) and the outlet contact group (131, 132) are mounted coaxially. By combining a soft connection and a hard connection, the electrical path utilizes the flexibility of the soft connection to make the mounting of the contact groups more flexible and convenient and utilizes the hard connection to obtain a reliable and stable electrical path, thus achieving a balance between assembly efficiency and assembly quality.

    摘要: The present invention discloses a protection device for electronic release. The protection device is connected to an energy storage capacitor of the electronic release. The energy storage capacitor is charged to a sufficient voltage when a primary loop current is a small current, which is 0.4ˆ¼0.8 times of a rated primary loop current. The sufficient voltage is 12Vˆ¼15V. The charging methods for the energy storage capacitor comprises a direct boost charging mode with resistance current-limiting or a PWM boost mode using a rechargeable battery. The present invention also discloses a protection method for electronic release. The protection device and the protection method for electronic release of the present invention charge the energy storage capacitor with extra electrical energy that exceeds a normal operation of a MCU unit. The energy storage capacitor can still be charged to a sufficient voltage when the current in the primary loop is a small current, so that the magnetic flux converter can generate an electromagnetic force that is large enough to trigger the release mechanism.

    摘要: A hysteresis power supply circuit, comprising: an input circuit (102), a switch combination circuit (104), a sampling and control circuit (108), a feedback circuit (106) and an output circuit (110). The input circuit (102) is connected to a power supply input terminal, and rectifies a power supply input and provides isolation protection for the input terminal. The switch combination circuit (104) is connected to the input circuit (102), and is turned on or off to control the output power of the power supply output terminal. The sampling and control circuit (108) samples the output voltage and compares the output voltage with the reference voltage, and controls the switch combination circuit to be turned on or off according to the result of the comparison. The feedback circuit (106) is connected between the switch combination circuit (104) and the sampling and control circuit (108). The switch combination circuit (104) outputs a positive feedback signal to the sampling and control circuit (108) through the feedback circuit (106), and the positive feedback signal causes a hysteresis effect on the comparison action of a reference power supply chip. The output circuit (110) is connected to the switch combination circuit (104), filters the output of the switch combination circuit (104) and provides isolation protection for the output terminal, and its output serves as an output of a hysteresis power supply circuit.
