Embodiment 1

[0064] refer to Figure 1 ~ Figure 3 , providing a schematic diagram of the overall structure of a secondary control cabinet for FTU testing, as shown in figure 1 A secondary control cabinet for FTU testing includes a cabinet body 100 and an interaction unit 200, an acquisition unit 300, a simulation unit 400 and a switching device M arranged in the cabinet body 100; the interaction unit 200 is a device for transmitting the first signal, And the interactive unit 200 is respectively connected with the analog unit 400, the acquisition unit 300 and the external console; the acquisition unit 300 collects the current, voltage and waveform of the device under test through the switching device M; the analog unit 400 receives the first signal, and The converted second signal is sent to the switching device M; and the switching device M receives the second signal of the analog unit 400 and performs a switching test according to it.

[0065] Specifically, the main structure of the pres...

Embodiment 2

[0070] Such as Figure 4~6 As shown, this embodiment is different from the first embodiment in that: the switching device M includes a processing unit 600, an interface unit 700 and a box body 800, and the processing unit 600, the interface unit 700 and the box body 800 cooperate with each other , can automatically switch modes (electromagnetic mode and small signal mode) according to the type of equipment to be tested when testing the equipment to be tested, and does not need to be re-wired. The degree of automation is high, which greatly improves the test efficiency and saves time and effort. Labor force, specifically, the switching device M includes a processing unit 600, an interface unit 700, and a box body 800. The box body 800 plays the role of protecting and carrying the processing unit 600 and the interface unit 700. Space N1; and the processing unit 600, which has the function of signal processing and regulation, is installed in the accommodation space N1; the connec...

Embodiment 3

[0076] refer to Figure 15 , this embodiment is different from the previous embodiment in that: the switch module 602 is divided into a binary output binary input mode 602a and a current voltage mode 602b. Considering the test requirements between the equipment to be tested and the measuring equipment, the practicability of the integrated access device is greatly improved. Specifically, the switch module 602 is divided into a switch mode 602a and a current voltage mode 602b, and the switch mode 602a and the current voltage mode 602b are connected to the control signal module 605 respectively.

[0077] Further, such as Figure 15 and 16 As shown, the current and voltage mode 602b includes an electromagnetic switching submodule 602b-1 and a small signal switching submodule 602b-2. The electromagnetic switching submodule 602a is connected to the small signal switching submodule 602b and is connected to the control signal module 605 respectively. of, such as Figure 10 and 18...

Abstract

The invention discloses a secondary control cabinet for FTU test, which comprises a cabinet body, and an interaction unit, a collection unit, an analog unit and a switching device arranged in the cabinet body. The interaction unit is a piece of equipment for transmitting a first signal, and is connected with the analog unit, the collection unit and an external console. The collection unit collectsthe current, voltage and waveform of equipment under test through the switching device. The analog unit receives a first signal, converts the first signal into a second signal and sends the second signal to the switching device. The switching device receives the second signal from the analog unit, and performs switching test according to the second signal. Through the cooperation of the interaction unit, the collection unit, the analog unit and the switching device, automatic switching connection test can be performed according to the type of FTU, time and labor are saved, and the efficiencyof FTU test is greatly improved.
