Abstract
The invention relates to an oil charging cable terminal with an insulating oil level testing function; and an oil charging port is connected with a pressure testing oil volume display unit through a communicating tube. According to the oil charging cable terminal with the insulating oil level testing function, the pressure testing oil volume display unit is arranged on the oil charging port of the oil charging cable terminal; the pressure and temperature of insulating oil are acquired constantly through a pressure sensing element in a pressure testing module and a temperature sensor in a temperature testing module; then calculation is carried out according to a formula P=Rho gh in a central control module; the level of the insulating oil is displayed on a display module which is arranged on a shell body constantly; and when passing by, an operator can intuitively see the level, temperature and other information of the insulating oil, so that the overhaul speed is greatly improved, and a work plan for later maintenance is made conveniently.
Description
Technical field
The invention belongs to Oil-filled Cable End structure field, especially a kind of Oil-filled Cable End that has the test of insulating oil liquid level.
Background technology
Oil-filled Cable End is the ejector of oil-filled cable two ends, its structure is: comprise insulating case and tail pipe, tail pipe is installed in the bottom surface of ring flange, insulating case is installed in this ring flange upper surface, in insulating case, fill insulating oil, make oil-filled mouthful at tail pipe, this oil-filled mouthful is used for replenishing of the interior insulating oil of insulating case.Oil-filled Cable End is occupied very big share because of its good insulation performance performance in HV cable accessories market, whether the abundance of the insulating oil between insulating case and the stress cone is the important prerequisite that guarantees insulation property.At present, whether operating personnel must careful inspection terminal have the phenomenon of leakage of oil when making an inspection tour, can't know the remaining oil mass of terminal inner accurately, can't formulate effective Maintenance and Repair plan, inconvenience very.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of Oil-filled Cable End that has the test of insulating oil liquid level rational in infrastructure, that show the insulating oil surplus constantly is provided.
The technical scheme that the present invention takes is:
A kind of Oil-filled Cable End that has the test of insulating oil liquid level, comprise insulating case, ring flange and tail pipe, the upper surface of ring flange and bottom surface are installed insulating case and tail pipe respectively, make oil-filled mouthful with the insulating case internal communication at tail pipe, it is characterized in that: described oil-filled mouthful by connecting a pressure measurement formula oil mass display unit communicating pipe.
And, described pressure measurement formula oil mass display unit comprises housing, pressure test module, display module and central control module, setting-in display module on this housing, this display module connects the input/output interface of the central control module of adorning in the housing, the input/output interface of this central control module also connects the pressure test module of adorning in the housing, and this pressure test module connects described oil-filled mouthful by pipeline.
And the input/output interface of described central control module also connects the temperature test module of adorning in the housing, and this temperature test module is inlaid in the described pipeline.
Advantage of the present invention and good effect are:
Among the present invention, oil-filled mouthful of installation one pressure measurement formula oil mass display unit in Oil-filled Cable End, by the temperature sensor in the pressure responsive element in the pressure test module and the temperature test module pressure and the temperature of insulating oil are gathered constantly, in central control module, calculate according to formula P=ρ gh then, the height of insulating oil liquid level is presented in the display module of installing on the housing constantly, when operating personnel through the out-of-date liquid level that can see insulating oil intuitively, information such as temperature, greatly improve inspection speed, be convenient to formulate the work plan of later maintenance.
