Description
Technical field
The utility model relates to a kind of charging set pick-up unit, especially for non-vehicle-mounted and Vehicular direct-current charging set electric property detection device.
Background technology
1. technical background: at present, known charging set test platform by electrical network, resistance wire, direct current sky open, oscillograph, accessory cables etc. partly form.Opening the different resistance gear of loading by manual adjustments direct current sky, is the charging set discharge.The testing staff manually records the result of correlation parameter, manual calculations correlation technique parameter in discharge process.This working method detects charging set and has drawback:
(1) line voltage can't be regulated, and does not reach the voltage-regulation scope of standard code; (the non-vehicle-mounted conduction-type charging set technical conditions of NB-T_33001-2010_ electric automobile)
(2) measuring accuracy is low, goes statistics by operating personnel, not only can not real-time data collection, and also measuring accuracy also can't guarantee;
(3) tester's workload is large, and efficient is low.A charging set electric property will be tested 8 ~ 9 data, and each data will be tested 3 times even more at least, get off like this tester only a charging set will test for a long time;
(4) safety coefficient is low, danger is large.Because the test resistance silk all is exposed, also the tester is in a kind of hyperbaric environment fully in the often wiring test test process, very easily has an accident.
2. the technical scheme example of prior art
Provide AC power by large electrical network for charging set to be measured, the direct current sky is opened the output of control charging set, and resistance wire is responsible for absorbing the output of direct supply, the electric parameter of oscillograph and the output of power analyzer test charging set.
Workflow: large electrical network provides alternating current for charging set to be measured, charging set output DC to be measured, dc voltage value and current value according to charging set output to be measured calculate resistance value, manual adjustments is to the resistance value that needs, then wiring loads, manual recording oscillometer and the relevant electric parameter of power analysis in loading procedure.Check according to the computing method in the GB whether its this electric property meets the regulation of existing standard according to the electric parameter of record at last.
In this testing scheme, electrical network directly export to charging set, can not satisfy regulation, the ohmic load in ± 15% scope of voltage-regulation scope in the testing standard and regulate also that inconvenient (do not measure a magnitude of voltage and current value all get manually go the regulating resistance load), all parameters all are to lean on the manual record of operating personnel, then in that whether calculate electrical property up to standard, and can not guarantee recorded position synchronization test value, cause precision on the low side; A unit for electrical property parameters is finished in test will close electrical network and charging set, again line regulating load, and electrical network and charging set are frequently opened in again start test.
In order to overcome the above problems, the utility model has been done useful improvement.
