Description
Technical field
The utility model relates to the mensuration of insulating material performance in appliance field, specifically a kind of volume resistance measurement mechanism of insulating material.
Background technology
Volume resistance be insulating material produce and use in, need a kind of key property of testing at any time, in the batch production and use procedure of material, general proving installation is megger, the volume resistance under room temperature state can only be measured, can not the volume resistance of detecting electric insulating material under the situation of being heated (as shown in Figure 2), for this reason, in insulating material production and use procedure, a kind of simple and practical proving installation is provided, Quick Measuring gets the volume resistance changing condition that insulating material is heated under situation, very important, the Potential performance defect of insulating material can be found early, prevent premature breakdown and the quality deterioration of electric product and electrical equipment and electrical product.
Utility model content
For the megger solving measurement volumes resistance in prior art can only measure the problem of the volume resistance under normal temperature, the utility model provides a kind of volume resistance measurement mechanism of insulating material, this device can measure the volume resistance of insulating material under different temperatures as required, particularly has very much 90 DEG C of actual use meaning--the measurement of the volume resistance of 220 DEG C of temperature ranges.
The utility model is the technical scheme solving the problems of the technologies described above employing: a kind of volume resistance measurement mechanism of insulating material, comprise the electrode anode and Electrode Negative that are connected with megger input and output port, insulating material to be measured is clamped between electrode anode and Electrode Negative, the upper surface of described Electrode Negative offers the groove holding insulating material to be measured, its inside is provided with heating element to heat insulating material to be measured, is provided with the temperature probe be connected with the temperature detection signal input port of temperature controller in the side of Electrode Negative.
Described heating element is electrothermal tube or electrical bar, and electrothermal tube or electrical bar are by the power take-off connection control of temperature controller.
Described heating element is 1-5 root general power is the electrothermal tube of 200-2000W, and heating element horizontal homogeneous be installed on bottom portion of groove to ensure homogeneous heating.
Beneficial effect: the utility model compared with prior art, has the following advantages:
1) effectively can carry out the volume resistance of insulating material under higher situation of being heated to detect, particularly there is very much the detection of 120 DEG C-220 DEG C of actual use meaning interval volume resistance performances, can continuously or under being interrupted taking temperature changing condition, the volume resistance change number of insulating material;
2) compact conformation; the bottom electrode metal component improved; both can as bottom electrode; also can as thermal source component part; can in certain accuracy range; more practical and carry out volume resistance detection easily, both can be used for that insulating material product export detects, user's routine use detects, also can be used for the online of material production line and do not shut down detection.
