Problems solved by technology
[0004] The use environment of the electric spark detector in the prior art is complicated, and it can be used both indoors and outdoors. However, the protection method of the operator wearing insulating protective gear is relatively subjective. When damaged during use, the discharge detection process of the EDM detector is likely to cause damage to the operator and reduce the safety during the detection process

The invention discloses a safety blocking type electric spark detector, which belongs to the field of coating leakage detection. The EDM detection probe matched with the set can effectively provide protection for the detection process when the operator uses the EDM detector body for detection through the cooperation of the voltage-sensing deformation sleeve, the weak current connection induction arc and the pre-blocking component. Establish a protective line for electricity safety. When the operator does not wear the standard or the insulating protective gear is damaged during use, the pre-blocking component is connected inductively to block the current flowing into the spark detection probe, effectively avoiding the current The damage caused by the continuous external discharge to the operator can improve the safety of the EDM body during use, reduce the damage caused by the reduction of personnel subjectivity, and then improve the protection of the EDM body.
Description
technical field [0001] The invention relates to the field of coating leakage detection, and more particularly, to a safety blocking electric spark detector. Background technique [0002] The electric spark detector, also named as the electric spark leak detector, the electric spark leak detector, etc., is mainly used to detect whether there are pinholes, blisters and other defects in the thick non-conductive substrate on the metal substrate. The use is very simple, one end is grounded, and the other end is a probe (many probe types include carbon brush type, circular spring type, flat rubber type), the electric spark detector mainly emits DC high voltage through the high voltage probe. When the layer surface, the instrument will automatically sound and light alarm. [0003] In the process of using the electric spark detector, it is generally the worker who holds the probe to conduct discharge detection on the non-conductive body on the metal substrate. Because of the live w...
