All this link of detection of electrical leakage will be carried out when existing residual current circuit breaker is produced, as shown in Figure 1, detected residual current circuit breaker is mainly connected by detection terminal with checkout equipment when detecting by operating personnel, in actual mechanical process, operating personnel sometimes careless two detection terminals touch together, cause short circuit, such checkout equipment can be burnt, if detected residual current circuit breaker internal short-circuit, also checkout equipment can be burnt, and be inconvenient to fix when residual current circuit breaker detects, work efficiency is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of detection protective device of residual current circuit breaker, to solve the problem.
In order to realize the purpose of this utility model, the utility model provides a kind of detection protective device of residual current circuit breaker, comprise checkout equipment and protective device, described protective device comprises three-pole breaker, two pole isolating switchs, insulcrete, guide rail, three-pole breaker and two pole isolating switchs are fixedly mounted on insulcrete by guide rail, the output terminal of described checkout equipment is connected with the input end of described three-pole breaker, the output terminal of described three-pole breaker is connected with the input end of described two pole isolating switchs, the output terminal of described two pole isolating switchs is connected with detection terminal and is respectively the first detection terminal and the second detection terminal.
Wherein, the output terminal of described three-pole breaker contacts with the input end of described two pole isolating switchs, forms inverted "L" shaped surveyed area between the two.
Wherein, the output terminal of described three-pole breaker is followed successively by the first output connection mouth, the second output connection mouth, the 3rd output connection mouth from left to right, the input end of described two pole isolating switchs, be followed successively by the first input wires mouth, the second input wires mouth from left to right, described first output connection mouth is connected by electric wire with described first input wires mouth, and described second output connection mouth is connected by electric wire with described second input wires mouth.
Wherein, described checkout equipment is remained current protector detector.
The utility model compared with prior art; when staff touches together by connecting a detection terminal because of carelessness; or during the residual current circuit breaker internal short-circuit be detected; the two pole isolating switchs detected in protective device will trip; checkout equipment so just can be protected not to be burned; and when detected residual current circuit breaker is single-pole circuit breaker; single-pole circuit breaker can be placed directly in the inverted "L" shaped monitored area that three-pole breaker and two pole isolating switchs are formed; fixation is played to single-pole circuit breaker, convenient detection.
Accompanying drawing explanation
