The product mainly applies in the electric power system and is used assorted to the sleeve tube. The product can prevent from exploding, be rebuilt in the scene without replacing the sleeve tube regularly and decrease the cost during the operation of the sleeve tube.
Description
Technical field: the utility model relates to a kind of Explosive proof Hanged Oil Tank, and this oil conservator is mainly used in the electric power system, uses with sleeve kit.
Background technology: the oil conservator that uses with sleeve kit in the prior art is structure as a whole, and is arranged on a sealing device at sleeve pipe top, is provided with oil and air collecting chamber in the system of sealing.Oil in the sleeve pipe does not directly contact with outside air, only contacts with the dry air of oil conservator top air collecting chamber, and sleeve pipe because current loss and dielectric loss are arranged, makes capacitor core produce heat when operation.The air that absorbs its airtight oil conservator inside, oil volume expansion back of heat is compressed.Otherwise realize compensation by compressed air expansion to oil volume.The problem of its existence: (1) oil conservator is arranged on the top of sleeve pipe, and apart from the ground height, the observation of on-the-spot transformation, installation and maintenance and oil level is very inconvenient.(2) inside pipe casing pressure is uncontrollable, jeopardizes safe operation.The oil that expands when oily temperature rise can make the air compression in the airtight oil conservator air cavity, and the interior voltage rise height of air cavity causes pressing in the sleeve pipe integral body and strengthens; When the sleeve pipe oiling, because of the misoperation oiling causes air cavity smaller volume in the oil conservator too much.When temperature raises, can in airtight oil conservator, produce extra supercharging with the oily swell increment of volume; Little when the sleeve pipe load current, when ambient temperature is low, the oil in the sleeve pipe can shrink, compressed air expansions that can rebound in the airtight oil conservator air cavity, thereby make air generation negative pressure in the air cavity; When the capacitance of bushing fuse hindered the generation overvoltage for some reason, this pressure that rises sharply was collected in the sleeve pipe and discharges nowhere.When reaching the withstand voltage limit of insulator, porcelain spare bursts and causes power outage and cause fire.(3) insoluble sealing problem causes that seepage and oil product descend.At this moment pressure in oily temperature rise makes in the sleeve pipe oil expand and produces, and release pressure nowhere in the airtight system can diminish the overall sealing performance of sleeve pipe.The seepage phenomenon appears in integral sealing level decline to making sleeve pipe unavoidably.And when producing negative pressure, seal bad sleeve pipe and can suck outside air, cause the water content of oil in the sleeve pipe and air content to increase, oil degenerates.This vicious circle brings hidden danger must for the safe operation of transformer.(4) can't be to sleeve pipe operational monitoring and early warning.Sleeve pipe is after operation, and power consumer can't be monitored operating sleeve pipe, can't take appropriate measures and means are eliminated accident in rudiment.Can only take to regularly replace the safe operation that sleeve pipe guarantees transformer, increase operating cost.
Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of good electric property is provided, and the Explosive proof Hanged Oil Tank of transforming is installed at the mechanical strength height and the scene of being convenient to.For achieving the above object, the utility model adopts following technical proposals: Explosive proof Hanged Oil Tank, comprise cover member (3), cover member (3) connects and composes cabinet by bolt (2) and loam cake (1) and chassis assembly (9), be provided with the expansion core component in the cabinet, the expansion core component is installed with the upper end cover (4), bottom end cover (7) and the lower linking tube assembly (8) that are provided with top connection (18) by core body (6) and forms, inner chamber at core body (6) is provided with spring (5), and the upper end of spring (5) is hung on lateral pin (15); The lower end is fixing by back-up ring (10), spring-hanging board (11), lower linking tube assembly (8) is connected with chassis assembly (9) with nut (13) by seal washer (12), above-mentioned joint (1 8) is connected with pointer (14) by nut (17), label (16) is housed on the pointer (14), plug screw (21) is by nut (22), and O RunddichtringO (19), (20) and top connection (18) are fastening.
Above-mentioned Explosive proof Hanged Oil Tank adopts with sleeve pipe and divides body structure, with its outer being hung under the sleeve pipe.The inner set metal bellow expander of oil conservator is with the variation convergent-divergent of oil temperature.Material is that stainless steel (1Cr18Ni9Ti) air penetrability is zero.Because stainless steel is a non-magnet_conductible material, does not generate heat so structurally be not subjected to electric field and influence of magnetic field.
Cubage compensation device during volume contraction or expansion that the utility model causes because of variations in temperature as a kind of iknsulating liquid or insulating gas has following characteristics: (1) explosion arrestment.Owing to cancelled air chamber, in airtight oil conservator, be full of oil entirely, solved the air in the chamber and can dissolve in the oil and make the gassiness of oil and the shortcoming of water content increase.Because the inside positive/negative pressure of sleeve pipe is absorbed and is discharged by the expansion of metal core body; make and be in constant voltage (pressure-fired) in the sleeve pipe all the time; guaranteed the overall sealing performance of sleeve pipe; the possibility of having stopped to bring seepage oil thus and having sucked outside air has been protected oil, and the electric property of oil is not reduced; prevent the short circuit blast; by pressure relief mechanism pressure release voluntarily, reach the explosion arrestment purpose when interior pressure is too high, security performance strengthens.(2) owing to adopt hermetically sealed split-type structural, with oil conservator place sleeve pipe below, be convenient to on-the-spotly transform, installation and maintenance; (3) reduce sleeve pipe operating cost, need not regularly replace sleeve pipe.
