Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] see figure 1 The block diagram of the basic working principle of the itinerant testing laboratory is shown. The experimental platform (or laboratory) is built on the basis of an on-site intelligent test vehicle platform, and consists of an industrial computer, a test standard device, a data acquisition module and a data processing module. The industrial computer is composed of a human-computer interaction unit and a processor. Experimenters input control instructions through the human-computer interaction unit, and the processor operates the test standard device according to the control instructions, and returns the test results to the human-computer interaction unit. The test standard device provides relevant standard quantities according to the instructions of the industrial computer. The data acquisition module selects an appropriate method ...

Abstract

A cyclic verification and test system for power transmission and transformation status maintenance and test devices comprises an industrial computer, a test standard apparatus, a data collection module and a data processing module. The test standard apparatus is connected to the industrial computer through a CAN bus. A data collection card, a digital multimeter and a manual input unit of the data collection module are connected to the test standard apparatus respectively. The data processing module comprises the following: a PCI interface, a GPIB interface and a USB interface. A data processing template library and a certificate template library are connected to a data processor respectively. The data collection card, the data multimeter and the manual input unit are connected to the PCI interface, the GPIB interface and the USB interface respectively. The data processor is connected to the industrial computer. The cyclic verification and test system for power transmission and transformation status maintenance and test devices has advantages of high reliability, high stability, high integrity density, easy to use onsite and the like, and can perform onsite inspection and test on power transmission status maintenance and test devices for a long period of time without interruption.

Description

technical field [0001] The invention relates to an itinerant verification experiment platform for power transmission and transformation state maintenance test equipment, especially for on-site calibration, verification and detection of power transmission and transformation state maintenance test equipment, that is, for AC and DC voltage dividers, loop resistance testers, high-voltage medium Loss tester, transformation ratio tester, zinc oxide arrester tester and on-load tap-changer tester and other power transmission and transformation condition maintenance equipment conduct reasonable and efficient on-site calibration, verification and testing. Background technique [0002] In recent years, with the vigorous development of electric power construction, new equipment in the power system is constantly emerging, and the influence of test results of high-voltage test equipment is also expanding. The quality of the data results is more and more valued by the power production depar...
