Abstract
The utility model relates to a tilted angle indication metrallic expander. The temperature indicating mechanism is composed of a push movable support and a pointer rod; a temperature indicating surface has an included angle with the vertical line of the ground; the limit position of the pointer rod is provided with a switch and an alarming device. The utility model is used on a high pressure transformer; the utility model has the advantages that the running inspectors of a substation can conveniently and clearly observe the position of the temperature indicating pointer under the high pressure transformer, and the temperature indicating mechanism can exactly reflect the change of the liquid temperature and the pressure in the high pressure transformer under the condition of atmospheric pollution and send out an alarm when the accumulation of fault pressure in the high pressure transformer exceeds the limit value.
Description
The utility model relates to high-voltage device equipment, is that liquid volume varies with temperature and a kind of compensator that has indication of changing in high-voltage mutual inductor and the power capacitor.
The temperature index plane of existing metal expander all is perpendicular to the ground, temperature indication is to be converted and got by the fluid pressure in the expansion box, the boxlike metal expander is contained on the high-voltage mutual inductor, when rolling inspection, the people stands in below the high-voltage mutual inductor, do not see high expander temperature indication pointer position more than 3 meters, the guide pin bushing of the temperature indication mechanical transfer mechanism of expander, slide block is in long-term humidity, oxidation can take place under the filthy atmospheric conditions, corrosion, sometimes have block transmission mechanism and in can not the correct response high-voltage mutual inductor temperature and pressure of liquid change, do not have the fault pressure warning unit simultaneously yet.
The novel purpose of this reality provides a kind of temperature index plane line perpendicular to the ground inclination angle type metal expander angle, that temperature indication transmission mechanism can not block, and has warning device.
The purpose of this utility model is achieved in that metal expander is made up of expansion box, connecting leg, the fuel feeding valve of finding time, temperature indicating mechanism, base plate and shell.Feature of the present utility model is that temperature indicating mechanism is made up of propulsion type moveable support and pointer bar, when liquid in the high-voltage mutual inductor increases with temperature or internal fault pressure, the corresponding mechanical displacement that expands of expansion box, the support of this mechanical displacement below expansion box passes to the pointer bar that has the propulsion type moveable support, pointer on the pointer bar is outwards motion upwards, pointer is the plane top offset of 15-30 degree angle at line perpendicular to the ground, makes temperature index plane line perpendicular to the ground that individual angle of inclination be arranged; Be provided with the warning device of being made up of switch and alarm in temperature indication limit value position, when there is fault high-voltage mutual inductor inside, its fault accumulation of pressure is to above high-voltage mutual inductor internal pressure permissible value the time, and the pointer bar is pushed down switch, opens alarm and gives the alarm.
Owing to adopt such scheme, temperature index plane line perpendicular to the ground has individual inclination angle, the substation operation inspection personnel is stood under the high-voltage mutual inductor, can be easily, clearly see temperature indication pointer position clearly, when high-voltage mutual inductor internal fault accumulated pressure reaches limit value, can give the alarm again, remind the operator on duty of transformer station to take measures, prevent the generation of high-voltage mutual inductor explosion accident, again owing to adopt movable support, from the expansion box to the temperature, all be simple fulcrum structure in the mechanical displacement transmission of indication pointer, can not be subjected to long term atmospheric corrosion and block, thereby can be chronically, correctly react the variation of interior fluid temperature of high-voltage mutual inductor and internal fault pressure.
Further specify the utility model below by accompanying drawing.
Fig. 1 is the utility model structural representation.
Among the figure 1, housing 2, spool 3, spring 4, shell 5, connecting leg 6, joint 7, base plate 8, expansion box 9, pointer bar 10, propulsion type moveable support 11, temperature indication pointer 12, temperature index plane 13, vertical line 14, index plane and vertical line angle 15, switch 16, alarm
The interior liquid volume of high-voltage mutual inductor varies with temperature and changes; its changing unit enters expansion box (8) by base plate (7) joint (6) and connecting leg (5); fluid temperature increases in high-voltage mutual inductor; volume increases expands expansion box; be connected in the downward push pointer bar of support (9) below the expansion box; the pointer bar drives propulsion type moveable support (10); travel(l)ing rest moves downward expansion box; convert upwards outwards motion of pointer to; temperature on pointer bar indication pointer (11) just moves upward on line perpendicular to the ground (13) has the temperature index plane (12) of 15-30 degree angle (14), demonstrates the temperature and the internal fault pressure of liquid in the high-voltage mutual inductor on protecting sheathing (4).When high-voltage mutual inductor internal fault pressure surpassed high-voltage mutual inductor internal pressure permissible value, pointer bar (9) was pushed down switch (15), switch open alarm (16), and alarm gives the alarm continuously; The fuel feeding valve of finding time of metal expander is to push down the spool (2) that has the rubber circle by housing (1), and spool dead spring (3), mat borrow the elastic force of spring to make rubber circle on the spool block the centre bore of housing and the valve that forms.Common state, finding time has a lid on the fuel feeding valve, when finding time oiling, the valve gap of outwarding winding inserts housing to the oiling instrument center pole of outside, its nut is spun on the external screw thread of housing, because oiling instrument center pole top bottom spool, make vacuum line or oil circuit by being communicated with the oiling of finding time, this process end in oiling instrument, find time fuel feeding valve and the expansion box, the oiling instrument withdraws from, because the effect of spring makes spool recover former sealing state.
Claims (3)
1, inclination angle indicating type metal expander, it comprises expansion box (8), connecting leg (5), the fuel feeding valve of finding time, temperature indicating mechanism, base plate (7), shell (4), it is characterized in that it is the 15-30 degree that temperature index plane (12) line perpendicular to the ground (13) has individual slanted angle (14), inclination angle, realize that inclination angle temperature indicative indication pointer displacement is propulsion type moveable support (10) and pointer bar (9).
