Abstract
The utility model belongs to the technical field of electric power equipment, and relates to an anti-seepage and torsion force-resistant terminal for a self-recovery electric power capacitor connecting leads, particularly to a connecting terminal. A terminal assembly is clamped in an installation hole of a cover. A lower end of the terminal assembly is sequentially sleeved with a sealing gasket and a standstill locking plate and is locked and fixed through a fastening nut. The terminal assembly comprises a guide rod and terminals which are moulded together, wherein the terminals are extended at two ends of the guide rod; and O-shaped sealing rings are disposed at contact positions of the terminals and upper end surfaces of the cover. According to the connecting terminal, since double-layered sealing rings are adopted, leakage of dipping material in the capacitor can be effectively prevented; since an all-in-one structure of the guide rod and the terminals is adopted, capability of torsion force of the guide rod can be effectively improved, the guide rod is prevented from getting broken or fallen off, and the leakage of the dipping material in the capacitor is prevented as well; and since the standstill locking plate is adopted, the terminals are effectively prevented from loosing or falling off. The connecting terminal is simple, safe and reliable in structure, good in sealing performance and convenient for assembling.
Description
Technical field
The utility model belongs to electrical equipment technical field, and the self-healing power capacitor that relates to a kind of antiseep, torsibility connects the terminal of lead, is specially a kind of binding post.
Background technology
Self-healing power capacitor (hereinafter to be referred as capacitor) is often referred to rated voltage at the capacitor of 1kV and following electric pressure.Its effect is in electric power system, with in parallel with electric loading, and the compensation reactive power of electric loading, to improve the power factor of electric power system, reduce feeder ear to the line loss between the electricity consumption end, thereby reduce electricity cost, and can alleviate the load of equipment, increase its useful life.
The conductor that binding post is connected in parallel as capacitor and electric power system, guarantee reliability and fail safe that lead connects, the capacitive reactive power electric current that guarantees capacitor is transported to electrical network, with the perceptual reactive current in the compensation network, play reactive power compensation to improve the effect of system power factor, also to guarantee the capacitor sealing simultaneously, guarantee that inner impregnated material can not seepage take place owing to the defective of binding post, jeopardizes the use safety of capacitor.Therefore the quality of connection terminal structure and performance directly has influence on safe and reliable operation and the useful life of capacitor.
The binding post of some capacitors, owing to adopt terminal surfaces training silver soldering to connect technology, the seepage phenomenon of the inside impregnated material that in capacitor assembling, installation, use, often takes place to come off between fracture between terminal and cap, guide rod and terminal and cause because of problems of welded quality, directly have influence on performance and the fail safe of capacitor, cause defectives such as capacitor heating, also can cause fire when serious.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of binding post simple in structure, ingenious, rational is provided, terminal and the guide rod of this binding post are one-body molded, sealing is reliable, can bear bigger installation torsion, can effectively avoid capacitor oil leakage phenomenon to occur in running simultaneously.
The technical scheme that provides according to the utility model: a kind of binding post, it is characterized in that: terminal assemblies is installed in the installing hole of cap, the terminal assemblies lower end is overlapped sealing filler ring and spline plate successively, and, be locked by clamp nut, described terminal assemblies comprises guide rod, the terminal that is embossed in together, and terminal is stretched out at described guide rod two ends, and described terminal and contact position, cap upper surface arrange the O RunddichtringO.
As further improvement of the utility model, described guide rod is embossed on the interior body of rod of terminal bulge-structure is set.
As further improvement of the utility model, described terminal upper end arranges the arc-shape winding groove, and the lower end is arranged in the installing hole of cap.
As further improvement of the utility model, described seal washer, spline plate are set in the terminal lower end successively.
The utility model compared with prior art, advantage is: (1) adopts the double-layer seal circle, can effectively prevent the seepage of impregnated material in the capacitor.(2) adopt guide rod and the integrated structure of terminal, can effectively improve the ability of the twisting resistance of guide rod, prevent the guide rod fracture or come off, and the seepage that prevents the interior impregnated material of capacitor.(3) adopt the spline plate, prevent that effectively terminal from becoming flexible, coming off.(4) the utility model is simple in structure, safe, reliable, and favorable sealing property is easy to assembly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is for using the status architecture schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, comprise guide rod 1, terminal 2, O RunddichtringO 3, cap 4, seal washer 5, spline plate 6, clamp nut 7, terminal assemblies 8, bulge-structure 9, groove 10 etc.
As shown in Figure 1, 2, the utility model is a kind of binding post, terminal assemblies 8 is installed in the installing hole of cap 4, terminal assemblies 8 lower ends are overlapped sealing filler ring 5 and spline plate 6 successively, and, being locked by clamp nut 7, described terminal assemblies 8 comprises guide rod 1, the terminal 2 that is embossed in together, terminal 2 is stretched out at described guide rod 1 two ends, and described terminal 2 arranges O RunddichtringO 3 with contact position, cap 4 upper surface.Guide rod 1 is embossed in plastics terminal 2, is combined into terminal assemblies 8, has both guaranteed the sealing between guide rod 1 and the terminal 2, has also strengthened the twisting resistance of guide rod 1 simultaneously.Secondly, use O RunddichtringO 3 and seal washer 5 simultaneously, and guarantee that terminal assemblies 8 effectively contacts with cap 4, clamp nut 7 is tightened fixing back O RunddichtringO 3 and is effectively reliably contacted with the position up and down of cap 4 with seal washer 5, reach the purpose that prevents the impregnated material seepage in the capacitor, simultaneously because the elastic acting force of seal washer 5, it is loosening to prevent effectively that clamp nut 7 from taking place, the spline plate 6 that installs additional is the position of stationary terminal 8 effectively, and can prevent guide rod 1 when connecting lead, possibility loosening even that come off takes place because being subjected to blackout torsion in terminal assemblies 8.
Guide rod 1 is embossed on the body of rod in the terminal 2 bulge-structure 9 is set, and can effectively increase the contact area of guide rod 1 with terminal 2, makes that both connections are tightr.
Terminal 2 upper ends arrange arc-shape winding groove 10, and the lower end is arranged in the installing hole of cap 4.
The utility model adopts the double-layer seal circle, can effectively prevent the seepage of impregnated material in the capacitor, adopt guide rod and the integrated structure of terminal, can effectively improve the ability of the twisting resistance of guide rod, prevent that guide rod from rupturing or come off, and the seepage that prevents impregnated material in the capacitor, adopt the spline plate, prevent that effectively terminal from becoming flexible, coming off, the utility model is simple in structure, safe, reliable, favorable sealing property, easy to assembly.
