Background
In order to ensure the safety of human bodies and the safety and reliability of power supply of equipment, related personnel of a power system need to carry out maintenance such as various operations or maintenance tests on the equipment in a charged area, operators carry out switching operation, testers carry out charged tests, and the maintainers carry out equipment maintenance and other work, and the work needs to be carried out by wearing insulating gloves and wearing insulating boots in the requirements of the electric power safety working rules.
The high-voltage insulating gloves are electrical safety articles, play a role in protecting hands or human bodies, are made of rubber, latex, plastics and other materials, and have the functions of electricity prevention, water resistance, acid and alkali resistance, chemical resistance and oil resistance. The device is suitable for the electric power industry, the automobile and mechanical maintenance, the chemical industry and the precise installation.
The high-voltage insulating gloves for live working are important components of insulation protection in individual protective equipment, and along with the development of the power industry and the popularization of live working technology, stricter requirements are provided for the use safety of the high-voltage insulating gloves for live working.
The insulating gloves are worn to avoid electric shock damage, so the protection function of the insulator is firstly determined by the magnitude of leakage current passing under a certain voltage, and if the leakage current is within the numerical scale of safe current, the leakage current is safe, otherwise the leakage current is unsafe. When a certain voltage is applied, although breakdown is not caused, excessive leakage current causes damage to the human body.
In winter, frost or high humidity, condensed water or running water is easy to appear, and when the water flows down along the high-voltage insulating gloves, the insulating strength of the high-voltage insulating gloves is reduced, and the electric shock probability is increased.
Chinese patent application No. 201410793419 discloses it includes insulating gloves body and bracelet formula high pressure detector of high pressure alarm function, bracelet formula high pressure detector includes bracelet form resin casing, detection coil and audio alarm circuit, detection coil coiling is on annular coil skeleton and with coil skeleton coaxial encapsulation together in bracelet form resin casing, the wrist at insulating gloves body is overlapped to the resin casing suit, and one side thereof is provided with the alarm circuit mounting box, audio alarm circuit's circuit board is installed in the alarm circuit mounting box, and detection coil's one end ground connection, a termination audio alarm circuit's trigger signal input. The high-voltage alarm device is combined with the insulating glove, so that dangerous voltage can be quickly detected and an audio alarm signal can be timely sent out, and the working personnel are effectively prevented from frequently contacting various power facilities and power devices such as buses, wires, switches, safety devices, distribution boxes and the like when carrying out power construction and maintenance operation due to negligence, illusion or error. In order to prevent electric shock, workers are generally provided with safety helmet type alarms, but electric shock casualty accidents caused by negligence, illusion or error of the workers cannot be avoided. The main reason is that the hands of the operator are often closest to the electrified facility when working, and the conventional safety helmet type alarm cannot detect dangerous voltage in time due to a long distance and sends out an alarm signal with time lag. The invention solves the problems of high-voltage detection and alarm, and does not make a contribution to the humidity detection and alarm processing of the insulating gloves.

The invention solves the problem of heating inside the glove, and does not contribute to the humidity detection and alarm processing outside the insulating glove.
The invention discloses an intelligent insulating glove auxiliary device and an early warning method, and relates to the intelligent insulating glove auxiliary device and the early warning method, which are applied to the field of live places and high-voltage tests of power systems. The structure is that the body is provided with an induction type high-voltage sensor and a microprocessor, and the induction type high-voltage sensor is connected with the insulator through a probe sheet; the induction type high-voltage sensor is connected with the microprocessor, and the microprocessor is connected with the buzzer and the power supply module.

The invention solves the problems of high voltage detection and alarm, but does not make any contribution to the detection of external humidity of the insulating gloves and the alarm processing.
In addition to this, there is a problem that the prior art cannot intercept and treat the condensed water and other running water outside the glove to prevent it from continuing to flow down, which would pose a threat to personal safety if the running water passed through the lower portion of the glove to form a leakage loop with the human body.
Therefore, a solution to the above problems is urgently needed.
