Description

technical field

[0001] The invention relates to a detection device, in particular to a microcomputer protection calibrator, which belongs to the field of fault detection. Background technique

[0002] At present, when the microcomputer protection calibrator is used for the test, it is generally carried out by a working group of more than three people. Generally, one person is responsible for the wiring of the microcomputer protection calibrator and is responsible for various binary input and binary output inspections. One person is responsible for debugging the parameter setting of the tester and The tester is used, and another person observes the abnormality and movement of the equipment in front of the protected device. Among them, the person in charge who checks the action behavior of the equipment in front of the protective device is responsible for directing other personnel in the group to conduct the test. The person in charge needs to direct, so he cannot directly co...

Examples

Embodiment 1

[0021] Such as figure 1 As shown, a merging unit 4 is set in the primary equipment area, and a microcomputer protection calibrator 1 is arranged next to the merging unit 4. The microcomputer protection calibrator 1 and the merging unit 4 are connected by a test line, and the microcomputer protection calibrator 1 There is a built-in wireless router 2, the power cord of the wireless router 2 is connected in series with the power cord of the microcomputer protection calibrator 1, and starts synchronously, so as to avoid separately arranging an extra power plug for the wireless router 2. A protection device 6 is installed in the protection room. The monitoring personnel carry the handheld device 3 in the protection room, and use the handheld device 3 to remotely control the microcomputer protection calibrator 1 while detecting the action of the protection device 6 .

Embodiment 2

[0023] Such as figure 2 As shown, a merging unit 4 is arranged in the primary equipment area, and a microcomputer protection calibrator 1 is arranged next to the merging unit 4. The microcomputer protection calibrator 1 and the merging unit 4 are connected by a test line, and the microcomputer protection calibrator The upper surface of the instrument 1 is provided with a groove 5 matching the base of the wireless router 2, the wireless router 2 is placed in the groove 5, and the wireless router 2 and the microcomputer protection calibrator 1 move synchronously, which is easy to carry. A protection device 6 is installed in the protection room. The monitoring personnel carry the handheld device 3 in the protection room, and use the handheld device 3 to remotely control the microcomputer protection calibrator 1 while detecting the action of the protection device 6 .

Embodiment 3

[0025] Such as image 3 As shown, a plurality of merging units 4 are set in the primary equipment area, and a microcomputer protection calibrator 1 is arranged next to each merging unit 4, and the microcomputer protection calibrator 1 and the merging unit 4 are connected by a test line. A wireless router 2 is placed near the microcomputer protection calibrator 1, and each microcomputer protection calibrator 1 is networked and connected into a whole through RJ45 network cable, optical fiber or wireless network connection. The wireless router 2 provides wireless WIFI, and each microcomputer protection calibrator 1 is connected into a network to form a whole, which is unified and wirelessly controlled by the handheld device 3, which can realize the synchronization of the test output of each split microcomputer protection calibrator 1, and solve the problem of intelligent substation. When the merging units 4 are distributed, a single microcomputer calibrator 1 cannot meet the test...
