I.Overview
Insulation boots and gloves are the necessary safety protection tools for the
operation and maintenance of power system. DL/T1476 "Regulations for preventive test
of electrical appliances for safety of electric industry" the test method and cycle of
common safety equipment such as insulating boots and gloves are stipulated.Insulated
boots and gloves voltage test, the cycle is half a year, the test process is not allowed to
break down, Simultaneously insulated boots leakage current is less than the limit value.
The instrument adopts multi-channel high voltage leakage current measurement
patent technology and wireless data communication technology to achieve the safe
measurement of high voltage leakage current purposes.Through the application of this
technology, the tester is completely isolated from the high-voltage system, which can
not only accurately measure the multi-channel high-voltage leakage current, but also
ensure the personal safety of tester.
In order to improve work efficiency, 6 or 8 samples can be tested at the same time.
In order to avoid repeated testing , the high voltage breaking patent technology is
adopted. During the process of testing, the breakdown samples can be separated from
the high pressure test system. No breakdown of the test continued until the test is
completed.
In order to cate to the requirements of the standard and reduce the labor intensity,
the company has developed the remote control electric insulation rod test support with
scale.Insulated rod holder can be electrically adjusted electrode distance by means of a
wireless remote control or a button on the device, Simultaneously it has a scale and
quantifies the segment length.Electrode using a combination of conductive foam, which
can achieve the effect of enclosing the insulation rod of test.
