Abstract

The invention relates to an integrated test method of a primary and secondary pole top switch set. A test system is included. The test method comprises the steps that electrical connection is established, communicating connection is established, precision testing is performed, integrated protection testing is performed, and a test report is generated. The test method has the advantages that signal input and collection for integrated testing of the primary and secondary pole top switch set are realized through the test system, and an input signal and a collected signal are analyzed, so that integrated testing of the primary and secondary pole top switch set is realized, and integrated precision testing and integrated protection testing of a power filtering and distribution pole top switch, a power distribution terminal, a mutual inductor and a primary and secondary connection cable on the primary and secondary pole top switch set is realized; coverage is comprehensive, and a blind area in quality control of the primary and secondary pole top switch set can be effectively eliminated; and the test system can detect voltage, current and electric energy precision as well as integrated protection of the primary and secondary pole top switch set, so that the automatic degree is high, manpower is saved, and detection efficiency is improved.

Description

technical field [0001] The invention relates to an integrated testing method for a primary and secondary complete set of on-pole switches. Background technique [0002] In the 10kV power distribution network of the power system, the separate design and installation of the switch on the traditional distribution column and the distribution terminal have problems in interface standardization, device integration, equipment miniaturization, and test standardization, resulting in low equipment matching. , Poor reliability. In the face of a large number of newly added primary and secondary complete sets of on-pole switches, there is currently no testing method for the quality control of primary and secondary complete sets of on-pole switches, resulting in blind spots in the quality control of primary and secondary complete sets of on-pole switches. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an integrated testing me...
