[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] Example 1, as Figures 1 to 4 As shown, a modular integrated high-explosive circuit breaker trolley includes a chassis 1. An electrical component back box 2 and a circuit breaker body 3 are mounted on top of the chassis 1. In this embodiment, the circuit breaker body 3 is a miniaturized high-voltage vacuum permanent magnet circuit breaker. The electrical component back box 2 contains a power module 4, a chassis controller 5, a protector 6, a circuit breaker controller 7, a relay 8, a gateway 9, and a micro-break switch 10, all fixedly installed inside. The power module 4 is connected to the chassis controller 5, the circuit breaker controller 7, and the protector 6 via the micro-break switch 10. The protector 6 is connected to the chassis controller 5 and the circuit breaker controller 7. The circuit breaker controller 7 is connected to the circuit breaker body 3 through the relay 8. The gateway 9 is connected to the chassis controller 5 and the circuit breaker controller 7 through the communication interface. The side of the electrical component back box 2 is provided with a micro-break switch operation window 11 and a network cable connection window 12. The micro-break switch operation window 11 corresponds to the micro-break switch 10, and the network cable connection window 12 corresponds to the gateway 9. A contact rod 13 is fixedly installed on the side of the circuit breaker body 3 away from the electrical component back box 2.

[0021] The power module 4 provides stable direct current power for each electrical component inside the electrical component back box 2. The chassis car controller 5 is used to control the movement of the chassis car 1, so that the chassis car 1 has two moving ways of electric and manual, and is integrated into the electrical component back box 2 through the chassis car controller 5 to form an integrated module. The protector 6 is used to detect the current, voltage and other parameters in the entire circuit, and when an abnormality is detected (such as overcurrent, overvoltage, undervoltage, etc.), a signal will be sent to the circuit breaker controller in time to cut off the circuit to protect the equipment and personnel safety. The circuit breaker controller 7 receives the signal from the protector 6 to control the opening and closing of the circuit breaker body 3, realizing the protection and control of the circuit. The relay 8 is used to receive the signal of the circuit breaker controller 7 to close or open the circuit, so as to play the role of isolation, conversion and amplification of the signal. The gateway 9 serves as a communication hub, and the gateway 9 is connected with the circuit breaker controller 7, the relay 8 and the protector 6 through a communication interface (such as RS485, Ethernet, etc.), collects and forwards data. Each electrical component is connected with a remote monitoring system or an upper computer to realize data transmission and remote monitoring.

[0022] Working principle:

[0023] In this embodiment, the power module 4, the chassis car controller 5, the protector 6, the circuit breaker controller 7, the relay 8, the gateway 9 and the micro switch 10 are integrated in the electrical component back box 2, and an almost closed box module is formed through the electrical component back box 2, thereby effectively reducing the probability of each electrical component being affected by external factors. The circuit breaker body 3 and the control circuit electrical components related thereto are all integrated above the chassis car 1, so that the overall structure is smaller in size and requires smaller high-explosion installation space compared with all the circuit breakers and corresponding control circuit electrical components on the market at present, so as to effectively form a modular structure. The contact rod 13 is fixedly installed on the side of the circuit breaker body 3 away from the electrical component back box 2, and the maximum size of the contact rod 13 is φ35, and the rated current is 1250A.

[0024] In addition, in this embodiment, a micro switch operation window 11 is opened at the corresponding position of the micro switch 10, so that the entire circuit breaker circuit can be quickly disconnected through the micro switch operation window 11, thereby enabling quick maintenance operation of the control circuit.

[0025] In embodiment two, as a further preferred scheme of embodiment one, the lightning arrester 14 is further fixedly installed on the upper surface of the chassis car 1, and the lightning arrester 14 is connected with the circuit breaker body 3. The lightning arrester 14 is used to protect the circuit breaker body 3 from lightning overvoltage, effectively resisting the threat of lightning and overvoltage, and ensuring the stable operation of the power equipment.

[0026] As a further preferred solution of the embodiment one, the inner cavity of the electrical component back box 2 is further provided with a fuse 15, which is connected in series between the circuit breaker controller 7 and the power module 4. The fuse 15 is used for short circuit protection and severe overload protection of the circuit. When a short circuit fault or a severe overload fault occurs in the circuit, the fuse 15 is heated by the current flowing through it, and the fuse melts when the melting temperature is reached, thereby breaking the fault circuit.

[0027] As a further preferred solution of the embodiment one, the micro-break switch operating window 11 is provided with a movable door 16 connected movably by a hinge, and a hanging ring is arranged on the outer side of the end of the movable door 16 away from the hinge. A hook 17 is arranged on the side of the electrical component back box 2, and the hook 17 is hung with the hanging ring. Therefore, when the internal circuit of the electrical component back box 2 needs to be repaired, the hanging ring on the outer side of the movable door 16 can be separated from the hook 17, so that the movable door 16 can be opened by rotating around the hinge, and the micro-break switch 10 can be operated to quickly break the entire circuit breaker circuit.

[0028] As a further preferred solution of the embodiment one, the inner cavity of the electrical component back box 2 is further provided with a resistor-capacitor 18 connected in series between the circuit breaker controller 7 and the power module 4. The resistor-capacitor 18 is used to effectively avoid overvoltage and overcurrent phenomena in the circuit, thereby effectively ensuring the normal operation and performance of the circuit.

[0029] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some of the technical features. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
