It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0015] The embodiment of the utility model relates to an intelligent detection device for handover test of power distribution equipment, such as Figure 1As shown, it includes a control module, a communication module, an intelligent switching module, an output module and a variety of test modules suitable for different handover test items.

[0016] The control module of this embodiment can be implemented by using a 51 series single-chip microcomputer, which includes a memory and a touch control screen. The memory stores test detection cases, and the touch control screen can display an operation interface. The control module communicates with a variety of test modules suitable for different handover test items and an intelligent switching module through a communication module to implement the issuance of control instructions, which are used to control the actions of each test module and the intelligent switching module to achieve automated detection. The operation interface displayed on the touch control screen has the functions of equipment control and safety measures prompts during the test detection process.

[0017] The communication module in this embodiment is composed of a switch and a time synchronization server device, which forms a communication network in the form of Ethernet communication to achieve data communication between the control module and the intelligent switching module, as well as various test modules suitable for different handover test items.

[0018] The various test modules suitable for different handover test items in this embodiment include one or more of a power frequency withstand voltage test module, an insulation resistance test module, a loop resistance test module, a mechanical property test module, a mutual inductor test module, and a power distribution terminal test module, which can generate the signal required for detection under the control instruction of the control module. The power frequency withstand voltage test module, the insulation resistance test module, the loop resistance test module, the mechanical property test module, the mutual inductor test module, and the power distribution terminal test module in this embodiment are all existing modules for the handover test items, and their structures are not described in detail here.

[0019] The core function of the intelligent switching module in this embodiment is to realize the switching of signal channels of different test modules. One end of the intelligent switching module is electrically connected to the output module through a test cable, and the other end is electrically connected to the power frequency withstand voltage test module, the insulation resistance test module, the loop resistance test module, the mechanical property test module, the mutual inductor test module, and the distribution terminal test module through the test cable. The intelligent switching module includes six signal channels, and the six signal channels are respectively connected to the power frequency withstand voltage test module, the insulation resistance test module, the loop resistance test module, the mechanical property test module, the mutual inductor test module, and the distribution terminal test module, that is, each signal channel is connected to a test module, wherein each signal channel is provided with a switch, and each switch is controlled by the control module. The intelligent switching module receives the control instruction issued by the control module to complete the signal channel connection of a single module of the power frequency withstand voltage test module, the insulation resistance test module, the loop resistance test module, the mechanical property test module, the mutual inductor test module, and the distribution terminal test module, so as to connect the signal required for detection generated by a certain test module to the output module.

[0020] The output module of this embodiment includes a voltage port, a current port, a ground port and a control signal port; the voltage port, the current port and the ground port are connected to the power distribution equipment to be tested through a primary test cable, and the control signal port is connected to the control signal port through a control cable.

[0021] When the intelligent detection device for the handover test of power distribution equipment of this embodiment is used, Figure 2 As shown, the following steps are included:

[0022] Step 1, connect the power distribution equipment to be tested with the intelligent detection device, specifically: connect the aviation plug at one end of the primary test cable to the voltage port, current port, and ground port of the output module of the intelligent detection device, connect the wire clamp at the other end of the primary test cable to the power distribution equipment to be tested, connect the aviation plug at one end of the control cable to the control signal port of the output module of the intelligent detection device, and connect the aviation plug at the other end of the control cable to the power distribution equipment to be tested.

[0023] Step 2: Find the corresponding test case from the memory of the control module of the intelligent detection device according to the type of the power distribution equipment to be tested. Assuming that the power distribution equipment to be tested is a pole-mounted circuit breaker, find the test case of the pole-mounted circuit breaker from the memory, which includes the detection process of the pole-mounted circuit breaker, such as performing a withstand voltage test first and then an insulation resistance test.

[0024] Step 3: The control module generates control instructions according to the process of the experimental test case, the intelligent switching module switches different signal channels according to the control instructions, and a variety of test modules suitable for different handover test items generate the signals required for detection according to the control instructions, and automatically complete the detection of different handover test items.

[0025] Taking the above-mentioned pole-mounted circuit breaker as an example, the control module first generates a first group of control instructions according to the process of the experimental detection case. The group of control instructions includes a control instruction for selecting the signal channel of the power frequency withstand voltage test module and a control instruction for turning on the power frequency withstand voltage test module. The control instruction for selecting the signal channel of the power frequency withstand voltage test module is sent to the intelligent switching module. After receiving the instruction, the intelligent switching module closes the switch on the signal channel connected to the power frequency withstand voltage test module and opens the switches on other signal channels to ensure that the signal channel of the power frequency withstand voltage test module is turned on. At the same time, the control instruction for turning on the power frequency withstand voltage test module is sent to a variety of test modules suitable for different handover test items. Among the multiple test modules suitable for different handover test items, only the power frequency withstand voltage test module receives the opening instruction. At this time, the power frequency withstand voltage test module automatically generates the voltage signal required for detection according to the opening instruction, and the other test modules are in a closed state. At this time, the voltage signal required for detection generated will be transmitted to the output interface along the signal channel connected to the power frequency withstand voltage test module, and transmitted to the pole-mounted circuit breaker by the output interface, thereby automatically completing the power frequency withstand voltage test of the pole-mounted circuit breaker. After a period of time (the time required for the power frequency withstand voltage test), the control module will generate a second set of control instructions, which include control instructions for selecting the signal channel of the insulation resistance test module and control instructions for turning on the insulation resistance test module. The control instructions for selecting the signal channel of the insulation resistance test module are sent to the intelligent switching module. After receiving the instructions, the intelligent switching module closes the switch on the signal channel connected to the insulation resistance test module and opens the switches on other signal channels to ensure that the signal channel of the insulation resistance test module is turned on. At the same time, the control instruction for turning on the insulation resistance test module is sent to a variety of test modules suitable for different handover test projects. Since only the insulation resistance test module among the multiple test modules suitable for different handover test projects receives the opening instruction, the power frequency withstand voltage test module is closed according to the received control instruction, and the insulation resistance test module is turned on. The other test modules remain in their original state. At this time, the insulation resistance test module automatically generates the current signal required for detection, and the current signal will be transmitted to the output interface along the signal channel connected to the power frequency withstand voltage test module, and then transmitted to the pole circuit breaker by the output interface, thereby automatically completing the insulation resistance test.

[0026] It is not difficult to find that the present implementation method deeply integrates the control module, communication module, various test modules, intelligent switching module and output module. Through one-time wiring, it can complete the automated testing of all handover test items, reduce manual intervention, improve detection efficiency, reduce detection difficulty, and greatly improve the detection quality and efficiency of the handover test.
