Technical field
The utility model relates to a kind of isolating switch, particularly a kind of GW7 type isolating switch with the rising binding post.
Background technology
GW7 type isolating switch is the outdoor high-voltage electrical equipment of the three-phase alternating current of the horizontal double break mouth structure of three pillar type, and it switches under no current-carrying situation for high-tension line and electric equipment such as high voltage bus, circuit breaker that quilt is overhauled and charged high-tension line carry out the usefulness of electrical isolation.Every group of isolating switch comprises three independently one poles, every utmost point has included base and insulator, three utmost points are distributed on the heavy vertical plane, the longitudinal length direction of three utmost points is parallel to each other, and is supporting insulator on two one poles in outer, and fixed contact and terminal block are installed on it, be used to connect high voltage bus, for the operation insulator, leading electric pole is installed on it on the middle one pole, the operation insulator is connected with motor drive mechanism by one group of transmission mechanism.When needs separating brake or combined floodgate, operation insulator and leading electric pole are driven under the effect of transmission mechanism and motor drive mechanism turns round certain angle on horizontal plane, realize the purpose of combined floodgate or separating brake to be connected or to separate with fixed contact.According to the designing requirement of power engineering, need the safe distance that keeps certain between high voltage bus that isolating switch connected and isolating switch fracture (fracture between leading electric pole and the fixed contact), otherwise will produce potential safety hazard, cause the generation of security incident.Fracture between the tie point of the fixed contact of prior art median generatrix and isolating switch and leading electric pole and the fixed contact is on the same horizontal line substantially, the influence that distance between fixed contact that bus connected and the leading electric pole is controlled and general layout distributes can not be excessive, if therefore busbar arrangement is above isolating switch, distance between the sag of this bus downlead and leading electric pole will be difficult to the distance that reaches safe, bus-bar frame generally can only be arranged in the outer of high voltage isolator in a closing surface for this reason, promptly is distributed in the outside of two outer one poles.Therefore, the prior art has following weak point: the integral arrangement mode of isolating switch has directly caused the change of transformer station's lateral separation big, thereby has enlarged the area of transformer station, has improved the cost of transformer station.
Invention constitutes
The purpose of this utility model is to overcome the deficiencies in the prior art part and a kind of arrangement that changes bus-bar frame is provided, and then the GW7 type isolating switch of the band rising binding post of closing surface lateral separation between reducing.
The utility model is realized by following approach:
The GW7 type isolating switch of band rising binding post, comprise three independently one poles, every utmost point has included base and insulator, three utmost points are distributed on the heavy vertical plane, the longitudinal length direction of three utmost points is parallel to each other, on two one poles in outer supporting insulator is arranged respectively, the static contact head device that is used to connect high voltage bus and equipment is installed on this supporting insulator, on the middle one pole operation insulator is arranged, on this operation insulator leading electric pole is installed, its structural feature is, also include a kind of binding post, itself and static contact head device mechanical connection, this binding post are installed in the supporting insulator top of outer one pole, and its longitudinal length direction is consistent with supporting insulator.
Like this, connecting the high voltage bus and the connecting line of isolating switch and the distance of relative position on short transverse between the isolating switch fracture has increased, thereby drawn back the distance between connecting line and the isolating switch fracture, in any case make the high voltage bus frame arrange, can guarantee that distance between connecting line and the isolating switch fracture is greater than safe distance, therefore also just dwindle the lateral dimension of transformer station's cubicle section, reduced the area of transformer station, reduced the cost of transformer station.
The utility model can further be specially:
Have two binding posts, be installed in respectively on the static contact head device of two outer one pole supporting insulators.
Have a binding post, be installed on the static contact head device of one of them supporting insulator in the two outer one poles.
That is to say, binding post two kinds of different schemes are installed, both can be installed in as required on the left or right one pole only two one poles one of them, also can on two one poles, this binding post be installed all according to the layout of transformer station.
The utility model can also further be specially:
Static contact head device includes terminal block and fixed contact, and binding post is installed in the terminal block top and is fastenedly connected with terminal block.
Or binding post is installed in the fixed contact top and is fastenedly connected with fixed contact.
Or binding post is installed in the terminal block top and is connected as a single entity with terminal block.
Or binding post is installed in the fixed contact top and is connected as a single entity with fixed contact.
Binding post can have multiple choices with being connected of static contact head device, or be connected with fixed contact, or be connected with terminal block, but reasonable mode is binding post and static contact head device to connect as one, like this, can reduce the contact resistance that produces when installing, thereby reduce the influence that the adding because of binding post produces isolating switch.
Binding post can further be specially:
The length of binding post is 0.8～2.0 meter.Wherein:
The binding post length of the isolating switch that the substation of 220KV is suitable for is 1.7～2.0 meters;
The binding post length of the isolating switch that the substation of 110KV is suitable for is 0.8～1.1 meter.
In order to guarantee the distance between line and the isolating switch fracture, the length of binding post needs can remain in certain scope, and best length should be:
The binding post length of the isolating switch that the substation of 220KV is suitable for is 1.8 meters;
The binding post length of the isolating switch that the substation of 110KV is suitable for is 0.9 meter.
In sum, the utility model mainly is to increase a kind of binding post on the supporting insulator of isolating switch, thereby in height draw back the distance of relative position between high voltage bus and the isolating switch fracture, guaranteed to maintain enough safe distances between the fracture of line and isolating switch, high voltage bus just can be arranged in the top of isolating switch as required like this, make the lateral separation of whole transformer station to shorten greatly, reduce the usable floor area of transformer station, reduce the cost of transformer station.
