Abstract
Provided is a testing arrangement for a train charger, comprising a detection terminal, a changeover switch, a current limiting tester, an over-charge tester, and an over-discharge tester, wherein the current limiting tester, the over-charge tester, and the over-discharge tester are respectively connected with the detection terminal via the changeover switch; an ammeter is serially connected between the detection terminal and the changeover switch; and a voltmeter is parallelly connected between the detection terminal and the changeover switch. The changeover switch controls the current limiting tester, the over-charge tester, and the over-discharge tester to correspondingly connect with the detection terminal for the detection of different projects by connecting the detection terminal to the charger, thereby allowing users to obtain the parameters of the charger under different detection projects via the ammeter and the voltmeter and accordingly determining whether the charger reaches the requirements or not. The testing arrangement simplifies the detection process of a charger and reduces the labor intensity for the operators.

The train charging set proving installation that the utility model provides, by detection terminal is connected on the charging set, for detecting different projects, switch control current limliting tester, overcharge tester and put tester connection corresponding to detection terminal with being connected, just can know the parameter of charging set under different test items by reometer with voltage table, thereby judge whether charging set reaches requirement, realize having simplified the testing process of charging set, reduced operating personnel's labour intensity.
Aforesaid train charging set proving installation, described current limliting tester comprise the first battery, the first swept resistance and the first resistance that is connected in parallel.
Aforesaid train charging set proving installation, the described tester that overcharges is electric capacity.
Aforesaid train charging set proving installation, described mistake are put tester and are comprised the second battery of being cascaded (battery of using and current limliting use be same battery) and the second swept resistance here.
Aforesaid train charging set proving installation, described reometer is connected between described switch and the described detection terminal by shunt.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do one to the accompanying drawing of required use in embodiment or the description of the Prior Art and introduce simply, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model train charging set proving installation embodiment;
Fig. 2 is that the utility model train charging set proving installation embodiment is in the circuit theory diagrams under the current limliting detected state;
