Background technology
Power transformation device oil-filled equipment need to often carry out sample analysis, to monitor oily acidity, granularity, viscosity and sulphur and content of copper ion etc., usually when oil-filled equipment is taken a sample, regulate the delivery valve door switch of oil-filled equipment and just can control oil with in the suitable speed inflow sampling jar, should avoid the oil sample long term exposure in air as far as possible, the artificial leakage of oil that causes because of misoperation in the time of more should avoiding taking a sample can further cause the pollution of environment He other equipment of transformer station.The valve switch size should suitably be controlled when sampling, if the speed of draining the oil is excessively slow, not only work efficiency is low, also can make the oil sample long term exposure in air, affects the degree of accuracy that oil product detects; If drain the oil excessive velocities, oil sample occurs easily to be spilt Lou and sputter, pollute electrical equipment and ground, and oil flows through the fast bubble that produces easily, also can affect accuracy of detection.But in the actual job process, sampling is generally the one man operation, is subjected to the restriction of the conditions such as device location, valve mass, personnel operation level, so that valve switch is restive, giving draws oil sample causes difficulty.
Summary of the invention
Flow through soon or the problems such as the oil sample sputter that causes excessively slowly and quality reduction because of oil in order to solve existing sampler, the invention provides a kind of transformer station oil-filled equipment sampling instrument, this instrument has very strong Anticorrosive Character, intensity is high, easy to operate, can adapt to the oil sample of different in flow rate and avoid the oil sample long term exposure in air.
For addressing the above problem, transformer station of the present invention oil-filled equipment sampling instrument comprises:
A kind of transformer station oil-filled equipment sampling instrument, described sampling instrument front end is the hollow cylindrical structure, the rear end is L shaped mozzle, described mozzle cross section is circular, wherein L shaped mozzle upper inlet is connected to the bottom, rear end of hollow cylindrical structure, the lower part outlet of L shaped mozzle connects sampling jar, described hollow cylindrical structure comprises the adsorption zone of front end and the buffer zone of rear end, wherein the port of adsorption zone is the fuel outlet valve interface, described fuel outlet valve interface is set to the inclined opening structure from upper left to the bottom right, evenly is provided with a circle magnet around the described fuel outlet valve interface; The top of described buffer zone arranges an opening near the position of fuel outlet valve interface, and the top of described opening covers a view window; Described L shaped mozzle comprises the vertical tube on top and the horizontal tube of bottom, and wherein the horizontal tube end is the sampling jar interface, is used for connecting sampling jar.
Further, described sampling instrument is whole to be made for stainless steel, and the hollow cylindrical diameter of movement of described sampling instrument front end is larger, and the diameter of L shaped mozzle is less.
Further, the plane of described fuel outlet valve interface and the angle of surface level are α, and wherein the scope of angle α is 60-75 °.
The good effect that the present invention has is closely sampling instrument to be combined with the metal wall of oil-filled equipment, thereby the liberation both hands are opened fuel outlet valve by a hand, and another is handed sampling jar, realizes that easily the one man operation draws oil sample.And view window be arranged so that the isolation of oil sample and extraneous air, have very strong Anticorrosive Character, intensity is high, can adapt to the oil sample of different in flow rate and avoid the oil sample long term exposure in air.

Among the figure: 1-fuel outlet valve interface, 2-view window, 3-mozzle, 4-sampling jar interface, 5-magnet, 6-fuel outlet valve, 7-oil-filled equipment, A-adsorption zone, B-buffer zone, the α-plane of fuel outlet valve interface and the angle of surface level
Embodiment
The present invention is described in detail below in conjunction with accompanying drawing 1-2.
A kind of transformer station oil-filled equipment sampling instrument, sampling instrument integral body is made for stainless steel, this sampling instrument front end is the hollow cylindrical structure, the rear end is L shaped mozzle 3, the mozzle cross section is circular, wherein L shaped mozzle 3 upper inlet are connected to the bottom, rear end of hollow cylindrical structure, and the lower part outlet of L shaped mozzle connects sampling jar.Wherein the hollow cylindrical diameter of movement of sampling instrument front end is larger, and the diameter of L shaped mozzle is less.This hollow cylindrical structure comprises the adsorption zone A of front end and the buffer zone B of rear end, wherein the port of adsorption zone A is fuel outlet valve interface 1, oil sample spills Lou and sputter in the sampling process, simultaneously be convenient to collect oil sample in order to form certain degree of tilt, fuel outlet valve interface 1 is set to be the inclined opening structure from upper left to the bottom right, the plane of fuel outlet valve interface 1 and the angle of surface level are α, wherein the scope of angle α can be 60-75 °, concrete angle can be selected different angles with flow velocity according to oil pressure, so that the outflow of oil and not spilling leakage.Adsorption zone A is adsorbed on sampling instrument on the oil-filled equipment by magnet 5, specifically be fixed on fuel outlet valve 6 places of oil-filled equipment, the setting position of magnet 5 is evenly to arrange around fuel outlet valve interface 1, and set-up mode can be the fixed forms such as bonding or embedding for being fixedly installed.On the top of buffer zone B near the position of fuel outlet valve interface 1 opening that a cross section is set is right-angled trapezium, observe for convenient, the hypotenuse of right-angled trapezium is near fuel outlet valve interface 1, right-angle side is arranged on the rear portion, cover a view window 2 on the top of opening, to avoid contacting of oil sample and air in the sampling process.
L shaped mozzle 3 comprises the vertical tube on top and the horizontal tube of bottom, and wherein the horizontal tube end is sampling jar interface 4, is used for connecting sampling jar.
When sampling, when at first sampling instrument being adsorbed on the metallic walls of oil-filled equipment 7, fuel outlet valve 6 is placed the centre position of fuel outlet valve interface 1, at this moment because the fuel outlet valve interface is the dip plane, sampling instrument integral body has a down dip to the right, because thereby both hands have been liberated in the absorption of magnet, then with a hand sampling jar is connected sampling jar interface 4, the another hand is opened view window 2, then opens fuel outlet valve 6 by spanner, then close view window 2, isolated oil sample contacts with the exposure of air, and oil sample flows out from fuel outlet valve 6, and adsorption zone A and buffer zone B flow through, by the sampling jar interface 4 of L shaped mozzle 3, flow in the sampling jar.When sampling finishes, adopt inverse operation to get final product.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
