There is more than one connector access port group. The connector access port groups are connected in series with each other. The connector access port groups are connected in parallel with a voltmeter and are connected in series with an ampere meter. The utility model discloses the tester specially used in the photovoltaic junction box. Circuit performance detection of the junction box is convenient.
Description
Technical field
The utility model relates to a kind of special-purpose current tester of photovoltaic terminal box.
Background technology
Photovoltaic junction box is between the solar cell array of solar module formation and the connector between the solar charging controller for electric consumption.After photovoltaic junction box completes, need to detect its performance, whether normal as current path, diode is subjected to the reverse characteristic in the thermal process after the excess current, in the prior art, current tester is to draw two probes, connects the electrode cable and the negative pole cable of terminal box respectively, promptly can only detect one by one, and connect by probe, detection efficiency is lower like this, and can't carry out other operations behind the hand gripping probe, such as switch etc., very inconvenient.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of special-purpose current tester that improves detection efficiency greatly.
The technical scheme in the invention for solving the technical problem is:
The special-purpose current tester of a kind of photovoltaic junction box, comprise the tester body, be provided with test circuit in the described tester body, the described test circuit reometer that is connected in series, described tester body is provided with display screen, also be provided with the connector access interface group that is electrically connected test circuit on the described tester body, described connector access interface group comprises the anodal port of matching connector positive pole and the negative pole port of matching connector negative pole, described connector access interface group is provided with more than one group, and be connected in series the described connector access interface group voltage table that is connected in parallel between the described connector access interface group.
As preferably, connector access interface group is provided with 8 groups.
As preferably, display screen comprises voltage display screen and electric current display screen.
The special-purpose current tester of a kind of terminal box is set, the connector access interface group of the connector of coupling terminal box is set on the tester body, and connector access interface group can be provided with 8 groups or other group numbers each other for being connected in series.During test,, be communicated with power supply, see the data of electric current display screen and voltage display screen, judge whether terminal box is qualified as long as the connector of terminal box is plugged into respectively on the negative pole port and anodal port of connector port group.
The beneficial effects of the utility model are: the utility model is provided with a kind of detector that is exclusively used in photovoltaic junction box, has made things convenient for the circuit performance of terminal box to detect.
