Embodiment
Referring to figs. 1 through Fig. 4, the tester embodiment that the utility model is used for overcurrent tripping isolating switch in control and protective switch is described further.
For a tester for overcurrent tripping isolating switch in control and protective switch, comprise overcurrent tripping isolating switch 5, cylinder 1, power supply 2, holder 3, indicating mechanism 4, test contact; Described overcurrent tripping isolating switch 5 comprises the solenoid 14 that energising produces magnetic force; the dynamic iron core of action is attracted by solenoid 14 magnetic force; and with the dropout plate 6 swung by dynamic iron core promotes; in view of in control and protective switch, overcurrent tripping isolating switch 5 part belongs to prior art, does not just repeat at this.
Described overcurrent tripping isolating switch 5 is fixed on holder 3, and preferred holder 3 coordinates clamping with overcurrent tripping isolating switch 5, when dropout plate 6 is threaded off, shell shakiness can not occur and eject holder 3; Described indicating mechanism 4 comprises switch and pilot lamp, described switch and dropout plate coordinated signals LED status, see Figure of description 2, one of dropout plate 6 is rectified switch, dropout plate 6 and dynamic iron core link, and by compressing switch during swing, thus control LED status, pilot lamp comprises red light 11 and green light 10, and pilot lamp connects power supply 2.
