Abstract
The utility model discloses a double-static contact 10KV disconnecting switch which is provided with double static contacts which are double-contact structures. The two ends of the static contacts are clamped by leaf springs; wherein one static contact is fixedly arranged on the connecting plate of a lead terminal on a static contact seat and the other is fixedly arranged at one side of the connecting plate of a lead terminal on a movable contact seat near the static contact seat; a dynamic contact is a double-metal plate separate structure; one end of the dynamic contact is fixedly arranged on the connecting plate of the lead terminal on the movable contact seat; after switching on, the two metal plates of the dynamic contact are respectively contacted with the same contact points of the two static contacts. The double-static contact 10KV disconnecting switch has a simple structure and is convenient to be operated; the double-static contact structure avoids the phenomena like overlarge resistance, heating and burning caused when a current passes through the connecting point of an axial structure. Meanwhile, the static contacts are double contacts and the dynamic contact is double-metal plates; the contact surfaces of the dynamic contact and the static contacts are increased from 2 to 8, which greatly improves the carrying capacity of the disconnecting switch and leads the disconnecting switch to run more stably.
Description
Technical field
The utility model relates to a kind of electric equipment, relates in particular to the 10KV isolating switch in a kind of 10KV of being applied to distribution network.
Background technology
The 10KV isolating switch is connected or the usefulness of insulating power supply as having under the uncharge situation of voltage at the 10KV distribution line.Because its simple in structure, simple operation is generally used as main element, use HGW9-12 (W)/630 type 10KV isolating switch the most generally at present in distribution line.Existing 10KV isolating switch has the following disadvantages: 1, moving, fixed contact adopts a side contact to connect the connected mode of a side shaft, the contact connecting portion of moving contact and fixed contact is got rid of the manual operation reason, general in conjunction with tight, difficult generation superheating phenomenon in service, and the axle connecting portion of moving contact and lead terminal connecting plate is because of its needs that rotate flexibly, connect not tight, in natural environment, move for a long time, because atmosphere, reasons such as rainwater corrosion, cause surface oxidation, reliable contact area reduces, and when electric current passes through, very easily produces because of resistance increases the contact point that causes and generates heat, the isolating switch burnout failure.2, moving contact (blade) adopts the bimetal leaf spiral spring to compress design, and fixed contact adopts the unitary piece of metal design, after the dynamic and static contact combination, by spiral spring dynamic and static contact contact-making surface is compressed, and contact area is little, and ampacity is little, and operation stability is poor.
Summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of moving contact to be connected closely with the movable contact headstock, two fixed contact 10KV isolating switches that dynamic and static contact contact area is big.
For finishing above-mentioned purpose, technical solution of the present utility model is: a kind of pair of fixed contact 10KV isolating switch, and it comprises base, be fixed on movable contact headstock and stationary contact headstock on the base, be separately fixed at lead terminal connecting plate, moving contact and fixed contact on movable contact headstock and the stationary contact headstock; Fixed contact is two, its double-contact structures that to be two ends clamped by leaf spring, and one of them is fixed on the lead terminal connecting plate on the stationary contact headstock, and another is fixed on lead terminal connecting plate on the movable contact headstock near an end of stationary contact headstock; Moving contact is that bimetal leaf divides body structure, and the one end is fixed on by axle on the lead terminal connecting plate of movable contact headstock, and behind the combined floodgate, the two metal sheets of moving contact contacts with the same terminal contacts of two fixed contacts respectively.
The utility model is simple in structure at original 10KV isolating switch, on the basis of simple operation, with the former pass that keeps apart by a side contact connects, a side shaft connects dynamic and static structure of contact terminal, change two static contact structures into, like this, even the reliable contact area of axle connecting portion of moving contact and lead terminal connecting plate reduces, its with the movable contact headstock on the lead terminal connecting plate between also have two contacts of fixed contact to contact, the resistance that has caused when having avoided because of electric current by the axle construction tie point is excessive, the generation of heating burnout phenomenon.Simultaneously, fixed contact is a double-contact, and moving contact is a bimetal leaf, and dynamic and static contact increases to 8 contact-making surfaces by 2 contact-making surfaces, has improved the ampacity of isolating switch greatly, makes its operation more stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, present embodiment comprises base 1, is fixed on movable contact headstock 11 and stationary contact headstock 2 on the base 1, is separately fixed at lead terminal connecting plate 10 and 3, moving contact 12 and fixed contact 13 on movable contact headstock 11 and the stationary contact headstock 2.Fixed contact 13 is two, it is double-contact 5,6 structures that two ends are clamped by leaf spring 4, one of them is fixed on the lead terminal connecting plate 3 on the stationary contact headstock 2 by screw, and another is fixed on lead terminal connecting plate 10 on the movable contact headstock near an end of stationary contact headstocks 2 by screw.Moving contact 12 is 7,8 fens body structures of bimetal leaf, and the one end is fixed on by axle 9 on the lead terminal connecting plate 10 of movable contact headstock, and behind the combined floodgate, the two metal sheets 7,8 of moving contact 12 contacts with the same terminal contacts of two fixed contacts 13 respectively.
