Description
Technical field
The utility model relates to the full-automatic analyzer device of a kind of insulating oil breakdown voltage, the full-automatic analyzer sample cup of especially a kind of insulating oil breakdown voltage.
Background technology
Insulating oil breakdown voltage is the important indicator characterizing insulating oil electrical equipment intensity, weigh the yardstick of insulating oil in inside electric appliance withstand voltage ability, it reflects in insulating oil whether exist moisture, impurity and electrically conductive particles and they on insulating oil impact the order of severity, conventional checkout equipment is insulating oil breakdown voltage detector, in existing insulating oil breakdown voltage detector, in sample cup, electrode and connected conducting rod are structure as a whole, when electrode or conducting rod damage, need to change together, change inconvenient, costly.
Publication number is CN202285040U, publication date is on June 27th, 2012, and name is called the Chinese utility model patent of insulating oil testing cup, discloses a kind of test lubricating cup of insulating oil breakdown voltage, the shortcoming of this utility model is conducting rod and resistance is integrative-structure, not easily changes.
Utility model content
The purpose of this utility model is to provide a kind of fixed bar and is connected with electrode replaceable, and part replacement is the full-automatic analyzer sample cup of insulating oil breakdown voltage easily.
The technical solution of the utility model is:
The full-automatic analyzer sample cup of insulating oil breakdown voltage, comprises glass cup, and glass cup both sides are provided with axle sleeve, it is characterized in that, axle sleeve one end is provided with electrode, and the other end is provided with dismountable fixed bar, are provided with resistance in the axle sleeve between electrode and fixed bar; Glass bowl cover is arranged at glass cup top, and glass cup, built with insulating oil, has two axle sleeves, two axle sleeves are fixed with electrode respectively, and two electrodes are relative, and electrode is immersed in insulating oil, electrode one end extend in axle sleeve, and electrode is connected with resistance, fixed bar, forms current path; Axle sleeve is material is insulating material, preferably plastics or rubber type of material; Described resistance is current-limiting resistance, can reduce load end electric current, prevents electric current to the damage of other parts.
Wherein, spring is provided with between fixed bar and resistance; Spring can regulate fixed bar to the pressure of resistance, make resistance and Electrode connection tight ness rating adjustable.
Wherein, fixed bar one end is provided with center pit, is provided with spring between fixed bar and resistance, and spring one end extend in center pit; Spring extend in center pit, facilitates spring position to fix on the one hand, spring also can be allowed to move with fixed bar, facilitate spring to take out when dismantling on the other hand again.
Wherein, fixed bar is connected with sleeve thread, and fixed bar is provided with O-ring seal; Fixed bar is connected with sleeve thread, is beneficial to fixed bar dismounting; O-ring seal makes fixed bar and sleeve sealing.
Compared with prior art, the beneficial effects of the utility model are: fixed bar is connected with sleeve thread, and structure is simple, connection is reliable, easy accessibility; Independently, it is convenient to change, and does not need integral replacing, reduces equipment use cost for fixed bar and each self-structure of the parts such as resistance, electrode.
