[0020] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model. Example 1
[0021] A dual-switching integrated protection box includes a terminal 1, a dual-switching module 5, a current detection module, and a voltage detection module.

The current detection module and the voltage detection module are electrically connected to the terminal 1 respectively.
[0022] To facilitate monitoring of the power distribution cables within the integrated protection box, this solution's double-switching integrated protection box is equipped with a terminal 1, a current detection module, and a voltage detection module. The current detection module works with the power distribution cable at the output end of the double-switching module 5, enabling it to collect the current value of the power supply path formed after the double-switching switch. The voltage detection module works with the power distribution cable at the input end of the double-switching module 5, which has two ports: one connected to the main power supply circuit and the other to the backup power supply circuit. The voltage detection module works with both the main and backup power supply circuits, collecting the voltage values of the main and backup power supply circuits before the double-switching switch. Both the current and voltage detection modules send the monitoring data to terminal 1, enabling monitoring of the power distribution cables within the integrated protection box.
[0023] In one alternative implementation, terminal 1 is powered by the power distribution cable at the input end of the double-switching module 5.
[0024] Terminal 1 has two power supply methods: external power supply and power supply cable. The power supply cable method connects the power supply cable to the power supply cable of the main power supply circuit and the power supply cable of the backup power supply circuit located at the inlet of the dual-switching module 5. The voltage detection module is also connected to the power supply cable of the main power supply circuit and the power supply cable of the backup power supply circuit located at the inlet of the dual-switching module 5 via power supply cables. The voltage signal is collected and the terminal 1 is powered by a set of power supply cables, which simplifies the cable laying in the integrated protection box.
[0025] In one optional implementation, the current detection module includes a current transformer 9 and a current monitoring circuit, the voltage detection module includes a voltage monitoring circuit, the terminal 1 includes a data processing component and a power management component, the current transformer 9 is electrically connected to the current monitoring circuit, the voltage monitoring circuit and the power management component are respectively electrically connected to the power distribution cable at the input end of the double-switching module 5 through monitoring cables, and the current monitoring circuit and the voltage monitoring circuit are respectively electrically connected to the data processing component.
[0026] Terminal 1 includes a housing and a circuit board located inside the housing. The circuit board has chips and circuit structures, forming a data processing component and a power management component. The current monitoring circuit of the current detection module and the voltage monitoring circuit of the voltage detection module are also located on the circuit board inside the housing of terminal 1, thus forming an integrated component. The housing of terminal 1 has several corresponding ports. The current transformer 9 of the current detection module is plugged into the corresponding port through the signal cable 13, thereby realizing the electrical connection with the current monitoring circuit. One end of the monitoring cable is plugged into the corresponding port of the voltage detection module, and the other end is connected to the power distribution cable of the main power supply circuit and the power distribution cable of the backup power supply circuit located at the input end of the dual-switching module 5, thereby realizing the voltage acquisition of the power distribution cable by the voltage detection module.
[0027] In one optional implementation, the power distribution cable at the input end of the dual-switching module 5 includes a main power distribution cable 3 and a backup power distribution cable 4, and two monitoring cables connected to the main power distribution cable 3 and the backup power distribution cable 4 respectively are connected in parallel to the power management component.
[0028] Terminal 1 is powered by both the main power distribution cable 3 and the backup power distribution cable 4. Specifically, one set of monitoring cables is connected to the main power distribution cable 3 and plugged into a corresponding port of terminal 1, allowing the voltage monitoring circuit within terminal 1 to obtain the voltage value of the main power distribution cable 3. The other set of monitoring cables is connected to the backup power distribution cable 4 and plugged into another corresponding port of terminal 1, allowing the voltage monitoring circuit within terminal 1 to obtain the voltage value of the backup power distribution cable 4. The two power supply circuits are connected in parallel, thus ensuring that the higher voltage path... The power supply circuit supplies power to terminal 1 after the power management component transforms and rectifies the voltage. For example, when both the main power distribution cable 3 and the backup power distribution cable 4 are energized, the power supply circuits of the two sets of monitoring cables are connected in parallel according to the circuit structure of the power management component, so that the power supply circuit with the larger voltage supplies power to terminal 1 after the power management component transforms and rectifies the voltage. When the main power distribution cable 3 is de-energized and the backup power distribution cable 4 is energized, the power supply circuit of the monitoring cable connected to the backup power distribution cable 4 supplies power to terminal 1 after the power management component transforms and rectifies the voltage.
[0029] Circuit breakers 2 are installed on the main power distribution cable 3 and the backup power distribution cable 4 respectively, and the two circuit breakers 2 are electrically connected to the data processing component respectively.
[0030] The status information transmission function of circuit breaker 2 is an existing design. Terminal 1 collects the status information of circuit breaker 2, which is installed on the main power distribution cable 3 and the backup power distribution cable 4 respectively, through the data processing component, and can transmit the information to the host computer through the communication component in terminal 1.

[0033] The integrated protection box of this solution has two surge protectors 6. One surge protector 6 corresponds to the main power distribution cable 3. Specifically, the output terminal of the circuit breaker 2 on the main power distribution cable 3 is equipped with a branching component, which is connected to the main direct power distribution cable 7, the protection cable of the surge protector 6, and the main power distribution cable 3 respectively. That is, the surge protector 6 is connected in parallel with the main direct power distribution cable 7 and the main power distribution cable 3, thereby providing surge protection for the main direct power distribution cable 7 and the main power distribution cable 3. The other surge protector 6 corresponds to the backup power distribution cable 4. Specifically, the output terminal of the circuit breaker 2 on the backup power distribution cable 4 is equipped with a branching component, which is connected to the backup direct power distribution cable 8, the protection cable of the surge protector 6, and the backup power distribution cable 4 respectively. That is, the surge protector 6 is connected in parallel with the backup direct power distribution cable 8 and the backup power distribution cable 4, thereby providing surge protection for the backup direct power distribution cable 8 and the backup power distribution cable 4.

The function of mounting plate 10 is to facilitate the installation and removal of the integrated protection box inside the box. In this solution, after the components such as terminal 1, double-switching module 5, circuit breaker 2 and surge protector 6 are installed on mounting plate 10, the mounting plate 10 can be placed into the box and fixed in place, thereby avoiding the problem of inconvenience in the installation and wiring of components due to the narrow space inside the box.
[0036] Among them, components such as terminal 1, double-cut module 5, circuit breaker 2 and surge protector 6 are installed on the first side end face 11 of the mounting plate 10. The first side end face 11 faces the opening side of the enclosure so that the operator can operate the components through the opening. The main power distribution cable 3, the main direct output power distribution cable 7, the protection cable of the surge protector 6, the spare power distribution cable 4 and the spare direct output power distribution cable 8 are also arranged on the first side end face 11 of the mounting plate 10.
[0037] At least a portion of the signal cable 13 between the components such as the dual-switch module 5, circuit breaker 2, and surge protector 6 and the terminal 1 is detachably mounted on the second side end face 12. After the signal cable 13 is electrically connected to the corresponding component via a port or other means, it passes through a hole on the mounting plate 10 near the corresponding component and extends to the second side end face 12 of the mounting plate 10. It is then fixed on the second side end face 12 by means of clips or other means and extends to the vicinity of the terminal 1. The corresponding port of the terminal 1 is located on the second side end face 12 of the mounting plate 10. The signal cable 13 is plugged into the corresponding port of the terminal 1, thereby achieving the separation of high-voltage and low-voltage electricity within the integrated protection box and preventing high-voltage electricity from interfering with the signal cable 13.
