Embodiment 2

[0031] According to the conditions described in Example 1, the diameter of the metal ball gap 8 is 100mm, and the height is 80mm; the material surface resistivity of the subconductor plastic protective cover 9 is 10 10 Ω. The potential measurement sensing probe 2 is used to collect the potential at the center of the ball, and the diameter of the ball at the top is 8mm. The insulating part 3 is used to ensure the insulation between the metal ball 8 and the potential measurement sensing probe 2, so as to ensure that the potential measurement sensing probe 2 can correctly reflect the potential at the center of the ball segment, and at the same time avoid oil in the metal segment 8 Intrusion into the oil-resistant rod6. The withstand voltage of the high voltage insulation test line 4 is 50000V. The grounding wire 5 is used to ensure that the potential of the metal ball gap 8 is zero potential. The oil-resistant rod 6 ensures that the oil does not invade into the oil-resistant r...

Embodiment 3

[0033] According to the conditions described in Example 1, only the subconductor plastic adopts a surface resistivity of 10 7 Ω subconductor material. The oil charge density display screen 12 displays the charge density of the oil in real time.

Abstract

The invention relates to a portable charge density measurement device for an oil product. The portable charge density measurement device mainly solves the problems that an existing charge density measurement device for an oil product is complex in design and inconvenient to carry. According to the portable charge density measurement device for the oil product, one end of a potential measurement sensing probe (2) is located in a metal ball segment (8), and the other end of the potential measurement sensing probe (2) penetrates through an oil-proof rod (6) and is connected with a charge density measuring instrument (7) through a high-voltage insulating test line (4); an insulating component (3) is located between the metal ball segment (8) and the potential measurement sensing probe (2); a ground wire (5) penetrates through the oil-proof rod (6) to make the metal ball segment be grounded; the high-voltage insulating test line (4) transmits electrostatic potential on the potential measurement sensing probe (2) to a potential measurement component (10) in the charge density measuring instrument (7), and then the electrostatic potential is processed and displayed. According to the technical scheme, the problems are well solved, and the portable charge density measurement device can be used for charge density measurement of oil products.

Description

technical field [0001] The invention relates to a portable oil charge density measuring device. Background technique [0002] In recent years, electrostatic accidents of oil products have occurred frequently. If the charge density of oil products can be easily measured, the staff can evaluate the electrostatic danger of oil products, so as to take effective preventive measures to avoid accidents, which is of great significance . [0003] Most of the light fuel oil is a high-insulation and easy-to-charge medium, and it is easy to accumulate charge and discharge during the canning and transportation operations of tank trucks, storage tanks and other containers. When the oil is pumped through the flow device, it can generate and retain a large amount of charge for a long time. When the charged oil is stored in the oil tank, the charge will accumulate in the oil. If the charge is accumulated enough , it will cause spark discharge, and may cause fire and explosion at the same t...
