Accompanying drawing explanation
The line insulation that Fig. 1 provides for the utility model embodiment and the structural representation of resistance test equipment;
Fig. 2 is the structural representation of the withstand voltage plug in embodiment illustrated in fig. 1;
Fig. 3 is the structural representation of the withstand voltage socket in embodiment illustrated in fig. 1.
Embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The line insulation that Fig. 1 provides for the utility model embodiment and the structural representation of resistance test equipment, Fig. 2 is the structural representation of the withstand voltage plug in embodiment illustrated in fig. 1, Fig. 3 is the structural representation of the withstand voltage socket in embodiment illustrated in fig. 1.As shown in FIG. 1 to 3, line insulation in the utility model embodiment and resistance test equipment comprise: pedestal 10, be arranged on the first housing 11 and the second housing 12 on pedestal 10, wherein, in the first housing, be provided with a plurality of withstand voltage plugs 111, in the second housing 12, be provided with a plurality of withstand voltage sockets 121, wherein, a plurality of withstand voltage plugs 111 difference are a plurality of withstand voltage sockets 121 one to one, and a plurality of withstand voltage plugs 111 pass by the hole (unnumbered in Fig. 1) on the first housing 11 and the second housing 12 respectively with the wire of a plurality of withstand voltage sockets 121; Wherein, the wire in a plurality of withstand voltage plugs 11 and a plurality of withstand voltage socket 12 is distinguished according to different voltage withstand class loop, draws guide line respectively after short circuit.
The line insulation that the utility model provides and resistance test equipment, uniqueness simple in structure, safety easy to use, can greatly save the setup time of cab control stand withstand voltage test, ensure the personal security in process of the test, guarantee product quality, thereby enhance productivity, save man-hour, reduce costs.
Further, above-mentioned embodiment illustrated in fig. 1 in, described voltage withstand class loop comprises: 110V loop, 24V loop, 220V loop.
Further, above-mentioned embodiment illustrated in fig. 1 in, described voltage withstand class loop is formed by the terminal short circuit of same color wire, and draws guide line.
Further, above-mentioned embodiment illustrated in fig. 1 in, in described a plurality of withstand voltage plugs and described a plurality of withstand voltage socket, be also provided with shielded point position and earth point position, described shielded point position and earth point position be any terminal wire of not crimping all.
Further, above-mentioned embodiment illustrated in fig. 1 in, described shielded point position is crimping lead wire not.
Below the use procedure of the utility model embodiment is described in detail.Before test, testing crew by appliances for labor protection in full rig, is lighted withstand voltage test district warning lamp, and validation test district is testing crew nothing but.Check that whether each parts ground connection is reliable, extract all plugs on cab control stand.Select a voltage withstand class loop, with crocodile clip shorting stub (not shown) short circuit all devices and instrument, disconnect all ground connection; The utility model embodiment is docked with the corresponding socket plug of product with the numbering of withstand voltage socket according to withstand voltage plug.And by other electric wiring, according to different voltage withstand class, require to carry out respectively short circuit.
During test, other loop ground connection, only use AC voltage withstand test platform test loop to be applied over the ground to the power-frequency withstand voltage of regulation, power-frequency withstand voltage should be applied to gradually trial value in 10s, keep trial voltage value 60s ± 5s, reduce to gradually 0 again, in process of the test without puncturing or flashover phenomenon is qualified.According to the method, can apply over the ground assigned voltage to other voltage withstand class loop and test.
