Slot type multi-point insulation detection device and method of insulated operating rod

Abstract

The invention discloses a slot type multi-point insulation detection device and method of an insulated operating rod. The device comprises a detection module and multiple slot type electrodes, and theslot type electrode is used to hold the insulated operating rod; and the detection module comprises a test power supply, a current detection unit and a microprocessor, the test power supply comprisesa DC power supply U0 and a high frequency interference resistant circuit, a voltage output by the DC power supply passes the high frequency interference resistant circuit and then a constant voltageis applied between two adjacent slot type electrodes, the current detection unit detects a current between the two adjacent slot type electrodes, and the microprocessor calculates the insulation resistance of part, between the two adjacent slot type electrodes, of the insulated operating rod according to the voltage of the DC power supply U0 and the current detected by the current detection unit.On the premise that an operator needs not to translate or rotate the insulated operating rod, insulation detection is carried out on the full surface of the insulated operating rod, and friction losscaused by measurement of the insulation resistance is avoided.

Description

technical field [0001] The invention relates to the technical field of insulation detection, in particular to an insulation operating rod slotted multi-point insulation detection device and method. Background technique [0002] Existing detection methods for insulating operating rods are mainly based on insulation resistance measurement. When the insulating coating on the surface of the insulating operating rod deteriorates, the insulation resistance decreases, and the insulating performance of the insulating operating rod can be judged by measuring the insulation resistance of the insulating operating rod. At present, the measurement methods are mainly divided into two types: the ring measuring electrode method and the slot measuring electrode method. Both measurement methods use two measuring electrodes to measure the insulation resistance of the operating rod between the electrodes to determine whether the surface insulation performance of the insulating operating rod be...

Problems solved by technology

[0003] The above methods all have one of the biggest disadvantages, whether it is moving horizontally or rotating the insulating operating rod, there will be friction loss between the measuring electrode and the insulating operating rod, which greatly reduces the service life of the insulating operating rod and the measuring electrode

In addition, the length of horizontal movement per unit times and the angle of rotation of the insulating operating rod are difficult to form a set of objective operating standards, and they are easily affected by the operator
