Abstract
The invention discloses a multi-source electromagnetic disturbance test equipment and a corresponding test method. When a first disturbance signal generator exists, an environment test box capable of adjusting the internal temperature and a second disturbance signal generator are selectively provided for providing multi-source electromagnetic disturbance. The multi-source disturbance test method can be achieved by changing the environmental temperature of to-be-tested equipment and changing the combination mode of a test port and a disturbance source in the electromagnetic compatibility immunity test, and the electromagnetic compatibility immunity test is enriched.
Description
Technical field
The invention belongs to power system automatic field, particularly relate to a kind of electromagnetic compatibility testing device and test method.
Background technology
Along with construction and the popularization of intelligent grid, merge cells, intelligent terminal, protective device, it is more and more general that the secondary devices such as measure and control device transfer on-the-spot application, because the installation site of transferring field apparatus is special, usually open air is installed on, below installed position primary equipment, transfer electromagnetism residing for field apparatus and climatic environment and the little indoor erecting equipment of control to have greatly changed, electromagnetic disturbance intensity increases greatly, the variation that electromagnetic disturbance approach also becomes, it is that the typical case of lowering device engineering site on the spot harasses model that secondary device is harassed in multiple harassing and wrecking source in the same time, conventional climatic environment and electromagnetic compatibility immunity are tested and can not be covered engineering site actual environment situation, therefore this patent incorporation engineering actual environment, fully verify transferring field apparatus, a kind of experimental technique of multi-source electromagnetic disturbance is proposed.
The compatible immunity experiment method of conventional electromagnetic as shown in Figure 1, normally test when indoor temperature is 25 degree, according to the difference of test port, select to be coupled accordingly decoupling network, and tested device is accessed with utility appliance the decoupling network that is coupled, then make tested device place duty, harassing and wrecking signal generator applies harassing and wrecking to tested device, the duty of process of the test finder by coupling decoupling network.This test method exist harassing and wrecking source with harassing and wrecking port unicity, can not completely analogue means in engineering site working condition.
Therefore, need a kind of new technical scheme to solve the problem.
Summary of the invention
The object of this patent solves the harassing and wrecking source problem single with harassing and wrecking port, and verification experimental verification covers and reduction engineering site actual environment situation.
For achieving the above object, the present invention can adopt following technical scheme:
A kind of multi-source electromagnetic disturbance testing equipment, comprise: the first harassing and wrecking signal generator, utility appliance of tested device, the first coupling decoupling network connecting tested device, connection first coupling decoupling network, and also comprise at least the first servicing unit and/or the second servicing unit; Wherein, the first servicing unit comprises environmental test chamber, and the temperature in environmental test chamber is adjustable, is provided with the insulcrete of carrying tested device in environmental test chamber; Second servicing unit comprises the second coupling decoupling network and connects the second harassing and wrecking signal generator of the second coupling decoupling network.
Corresponding, the test method of use multi-source electromagnetic disturbance testing equipment is: make described first harassing and wrecking signal generator provide the harassing and wrecking signal comprising power interruption, the first fast transient signal, the first surging signal, the first wave of oscillation signal, Conducted Radio Frequency; If there is the first servicing unit, then the temperature in adjusting ambient chamber; If there is the second servicing unit, then make the second harassing and wrecking signal generator provide to comprise the harassing and wrecking signal of power work range regulation signal, the second fast transient signal, the second surging signal, the second wave of oscillation signal.
