Utility model content
The purpose of this utility model is defect for prior art and deficiency; there is provided a kind of structure simple; RCD reasonable in design, easy to use, realizes while client does not have a power failure, and can test leakage protection alternating-current contactor performance again.
For achieving the above object, the technical solution adopted in the utility model is:
RCD described in the utility model, comprise casing and case lid, casing one end and case lid one end are hinged, described casing is provided with mounting bracket and panel, described mounting bracket is provided with isolating switch, described isolating switch is arranged on immediately below panel, nestedly on described panel be provided with converter, electric power overflow performance tester and three groups of electrical connectors, described converter one end is connected with the input end of isolating switch by wire, and the described converter other end is connected by the input end of wire with electric power overflow performance tester; Described electrical connector one end is fixedly connected with the copper bar of isolating switch through after panel.
Further, described electric power overflow performance tester is provided with liquid crystal display and printer.
Further, the two ends, left and right of described casing are symmetrical arranged jug.
After adopting said structure, the utility model beneficial effect is: RCD described in the utility model, comprise casing and case lid, casing one end and case lid one end are hinged, described casing is provided with mounting bracket and panel, described mounting bracket is provided with isolating switch, described isolating switch is arranged on immediately below panel, nestedly on described panel be provided with converter, electric power overflow performance tester and three groups of electrical connectors, described converter one end is connected with the input end of isolating switch by wire, the described converter other end is connected by the input end of wire with electric power overflow performance tester, described electrical connector one end is fixedly connected with the copper bar of isolating switch through after panel.When using the utility model; isolating switch input end in this device is connected with the input end of A.C. contactor in panel box by wire; isolating switch output terminal in this device is connected with the output terminal of A.C. contactor in panel box by wire; thus panel box is stopped power supply instantaneously when can not cause test protector; be very easy to tester, also can not affect other work because of test job.It is simple that the utility model has structure, arranges rationally, the advantages such as cost of manufacture is low.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Figure 1-3; RCD described in the utility model; comprise casing 71 and case lid 72; casing 71 one end and case lid 72 one end are hinged; described casing 71 is provided with mounting bracket 8 and panel 10; described mounting bracket 8 is provided with isolating switch 3, and described isolating switch 3 is arranged on immediately below panel 10.
Nestedly on described panel 10 be provided with converter 4, electric power overflow performance tester 6 and three groups of electrical connectors 2, described converter 4 one end is connected by the input end of wire with isolating switch 3, and described converter 4 other end is connected by the input end of wire with electric power overflow performance tester 6; Described electrical connector 2 one end copper bar 9 that is rear through panel 10 and isolating switch 3 is fixedly connected.
On panel 10 nested be provided with converter 4, by each phase of switch (A/B/C three-phase) go between to converter 4, the value just can being measured each phase by rotation converter 4 to relevant position.
Further, described electric power overflow performance tester 6 is provided with liquid crystal display 61 and printer 62.
Further, the two ends, left and right of described casing 71 are symmetrical arranged jug 1, can be convenient for carrying like this, handled easily.
When test leakage current and the electric leakage time of leakage protection alternating-current contactor in external panel box 11 with electric power overflow performance tester time; leakage protection alternating-current contactor tripping operation power-off in panel box 11; electric current is powered to user side via the isolating switch of wire in RCD, ensure that user side can not cause power-off because of leakage protection alternating-current contactor tripping operation in test panel box.
Electric power overflow performance tester is also referred to as leakage current tester.
The utility model can ensure that client does not have a power failure, and can measure again electrical leakage and the actuation time of each phase of threephase switch, and all right printout test result, has several functions.
The utility model adopts the portable knapsack design of casing, by integrated to connecting line, moving contact, switch and other devices, effectively reduce heavy burden, alleviates workload.
When using the utility model; isolating switch input end in this device is connected (as shown in Figure 3) by wire with the input end of A.C. contactor in panel box; isolating switch output terminal in this device is connected with the output terminal of A.C. contactor in panel box by wire; thus panel box is stopped power supply instantaneously when can not cause test protector; be very easy to tester, also can not affect other work because of test job.In addition, this structure is simple, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
