Description
Technical Field
The invention relates to the field of electrical equipment, in particular to an isolating switch and a control method and a control device thereof.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
As is well known, an isolating switch is a switching device used for isolating a power supply, switching operation, and switching on or off a small current circuit. When the isolating switch is in the opening position, an insulation distance meeting the specified requirements and an obvious disconnection mark are arranged between the static contact and the moving contact; when the isolating switch is in the closing position, the switch equipment can bear the current under the normal loop condition and the current under the abnormal condition within the specified time. The reliability of the isolating switch plays a vital role in the design, establishment and safe operation of a substation and a power plant.
At present, most of the existing isolating switches adopt a rotary or gravity type opening and closing structure. For example, fig. 1 shows a disconnecting switch using a rotary switching-on/off structure, and fig. 2 shows a disconnecting switch using a gravity switching-on/off structure. As shown in fig. 1, the opening or closing operation of the rotary isolating switch is realized by rotating the second insulator 102 through the operating structure 104 to drive the second blade 103-2 disposed on the second insulator 102 to be separated from or closed with the first blade 103-1 disposed on the first insulator 101; as shown in fig. 2, the gravity type disconnecting switch is operated by operating an operating mechanism 204 on a base rail to drive a third insulator 205 to lift or lower a first blade 203-1 on a first insulator 201, so that the third insulator is separated from or closed to a second blade 203-2 on a second insulator 202.
As can be seen from fig. 1 and 2, the rotary isolating switch drives the knife switch to be switched on and off through the rotation of the insulator, the gravity isolating switch drives the knife switch to be switched on and off through the multipoint transmission, and both the rotary isolating switch and the gravity isolating switch require a large distance between the insulators, so that the length of the knife switch is long, and an operating mechanism is required to output a large torque, so that the situation that the switching on and off is not in place or the insulators are broken can often occur.
In view of the above problems, no effective solution has been proposed.

The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

Reference to the description of the terms "one embodiment," "a particular embodiment," "some embodiments," "for example," etc., means that a particular feature, structure, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the application. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. The sequence of steps involved in the embodiments is for illustrative purposes to illustrate the implementation of the present application, and the sequence of steps is not limited and can be adjusted as needed.
The embodiment of the invention provides an isolating switch which can be but is not limited to a contact net isolating switch.
Fig. 3 is a schematic diagram of an isolation switch in an opening state provided in an embodiment of the present invention, and fig. 4 is a schematic diagram of an isolation switch in a closing state provided in an embodiment of the present invention.
As shown in fig. 3 and 4, an isolation switch provided in an embodiment of the present invention may include: a first insulator 301, a second insulator 302, a first blade 303-1, a second blade 303-2, an operating mechanism 304, a rotating shaft 305 and a base 306.
The lower end of the first insulator 301 is fixedly mounted on the base 306, the lower end of the second insulator 302 is rotatably connected with the base 306 through a rotating shaft 305, and the axis of the rotating shaft 305 is perpendicular to the plane formed by the axes of the first insulator 301 and the second insulator 302; a first blade 303-1 is arranged at the upper end of the first insulator 301, and a second blade 303-2 is arranged at the upper end of the second insulator 302; the operating mechanism 304 is disposed at a side of the second insulator 302, and configured to drive the second insulator 302 to rotate clockwise or along the rotating shaft 305 or the inverting pin, so as to realize an opening or closing operation of the second blade 303-2 and the first blade 303-1.
As can be seen from fig. 3 and 4, the operating mechanism 304 moves linearly up and down to drive the second insulator 302 to swing left and right, and the swinging second insulator 302 carries the second blade 303-2 to separate from or close to the first blade 303-1, thereby implementing the switching operation. Optionally, the operating mechanism 304 in the embodiment of the present invention is an electric operating mechanism, and the movement of the electric operating mechanism may be controlled by an external control device, so as to implement the opening or closing operation of the disconnecting switch.
In the disconnecting switch shown in fig. 1, during the switching-on and switching-off operation, the transmission part bears great radial load and great axial load; in the disconnecting switch shown in fig. 2, in the process of switching on and off, multi-point rotation is required for transmission, which results in low transmission efficiency. In the disconnecting switch provided by the embodiment of the invention, the axis of the rotating shaft is perpendicular to the plane formed by the axes of the first insulator 301 and the second insulator 302, that is, the rotating shaft with a transverse structural design is adopted, so that only radial load is applied to the rotating shaft instead of axial load in the switching-on or switching-off operation process, and the phenomenon that the rotating shaft is corroded due to rainwater and other liquid flowing into the transmission part, so that the transmission part is rusted and damaged can be effectively avoided. In addition, the insulator is driven to rotate to realize the opening or closing operation of the isolating switch, the transmission operation is simple, and the transmission efficiency is high.
Optionally, in the disconnecting switch provided in the embodiment of the present invention, the operating structure may adopt an operating force arm with an extended length, for example, more than one time of the operating force arm of the existing disconnecting switch.
According to the embodiment of the invention, the operating mechanism with a lengthened force arm is adopted to replace the rotary opening and closing isolating switch structure shown in figure 1 and the multi-position transmission opening and closing isolating switch structure shown in figure 2, so that the ratio of driving and driven torque during opening and closing operation is reduced, the requirement on the output torque of the operating mechanism is lowered, the effective action of the opening and closing operation is ensured, the reliability is improved, the service life is prolonged, and the problems of poor contact or missing of the opening and closing operation and the like are avoided. In addition, the movement mode of the operating mechanism in the embodiment of the invention is vertical linear movement, and the operation is simple.
Compared with the existing disconnecting switch, in the disconnecting switch provided by the embodiment of the invention, the spacing distance between the first insulator 301 and the second insulator 302 can be smaller. The isolating switch provided by the embodiment of the invention shortens the spacing distance between the first insulator 301 and the second insulator 302, so that the length of the switch blade is reduced, and the cost of raw materials for manufacturing the switch blade is saved.
As can be seen from the above, in the disconnecting switch provided in the embodiment of the present invention, the first insulator 301 is fixedly installed on the base, and the second insulator 302 is rotatably installed on the base through the rotating shaft 305, and as the axis of the rotating shaft 305 is perpendicular to the plane formed by the axes of the first insulator 301 and the second insulator 302, when the operating structure 304 drives the second insulator 302 to rotate clockwise or along the rotating shaft 305 or along the reverse needle, the opening or closing operation of the second blade 303-2 and the first blade 303-1 is achieved.
According to the isolating switch provided by the embodiment of the invention, the operation structure drives the insulators to rotate so as to realize the switching-off or switching-on operation of the isolating switch, the spacing distance between the insulators is shortened, and the requirement on the output torque of the operation structure is reduced. In addition, because the embodiment of the invention uses the insulator swing arm mode to carry out switching on and off, the moving distance of the switching on and off is changed by the position change of the insulator instead of the position change of the all-copper knife switch, thereby greatly reducing the using amount of copper, and achieving the effects of saving non-ferrous metal resources and reducing economic cost.
In an embodiment, in the disconnecting switch provided in the embodiment of the present invention, the first insulator 301 and the second insulator 302 may adopt an umbrella structure. Optionally, in the embodiment of the present invention, the first insulator 301 and the second insulator 302 are umbrella-type structures composed of a core rod, a sheath, and an umbrella skirt. It should be noted that, the core rod, the sheath and the shed which constitute the insulator in the embodiment of the invention are integrally formed, and the deformation-resistant external force is up to 6000KN, so that the insulator is firm and reliable.
According to the embodiment of the invention, the insulator with the umbrella type structure is adopted, so that sundries such as rainwater can be prevented from entering between umbrella skirts on the insulator, and the insulator can reliably work in severe weather such as rain, fog, snow and the like.
Optionally, in the embodiment of the present invention, the first insulator 301 and the second insulator 302 are made of a composite material.
Because the insulator of the existing isolating switch usually adopts ceramic materials, the insulator adopting the composite materials in the embodiment of the invention not only has the advantages of high mechanical strength, light weight, good insulating property and the like, but also can avoid the damage caused by explosion.
In one embodiment, the isolation switch provided in the embodiment of the present invention may further include: and a shield 307 disposed over the first insulator 301 and the second insulator 302.
Optionally, the cross section of the protective cover 307 adopted in the embodiment of the present invention is triangular. Fig. 5 is a schematic view of a protective cover provided in an embodiment of the present invention, and as shown in fig. 5, in the embodiment of the present invention, the protective cover having a triangular structure can prevent the protective cover from being damaged due to accumulation of impurities such as rain water on the protective cover.
In an embodiment, in the disconnecting switch provided in the embodiment of the present invention, the first blade 303-1 and the second blade 303-2 are connected in a clamping manner. Optionally, the first blade 303-1 is an inner clamping blade and the second blade 303-2 is an outer clamping blade.
In order to ensure that the first blade 303-1 and the second blade 303-2 are fully contacted when the first blade 303-1 and the second blade 303-2 are connected in a clamping manner, in an embodiment, the disconnecting switch provided in the embodiment of the present invention may further include: and the spring lock 308 is arranged on the second switch blade 303-2 and used for locking the second switch blade 303-2. The embodiment of the present invention can sufficiently contact the outer clip type blade (the second blade 303-2) with the inner clip type blade (the first blade 303-1) by applying a clamping force to the outer clip type blade (the second blade 303-2) through the latch provided on the outer clip type blade (the second blade 303-2). In addition, the outer clamping type switch blade is a clamp, so that the outer clamping type switch blade is easy to deform after being used for multiple times, and the outer clamping type switch blade can be prevented from deforming through the spring lock.
Optionally, in the embodiment of the present invention, the latch 308 is implemented by using a high strength stainless steel spring, so as to improve reliability of the disconnecting switch, and have the advantages of durability and rust resistance.
Fig. 6 is a schematic view of a latch according to an embodiment of the present invention, and as shown in fig. 6, a latch 308 provided on an outer-clip type blade according to an embodiment of the present invention may include: the distance between the two clamping pieces of the outer clamping type knife switch is a certain distance (the threshold value of the distance is smaller than or equal to the distance between the clamping pieces when the isolating switch is in a closing state) through the supporting piece, when the closing operation is executed, the inner clamping type knife switch is clamped by the outer clamping type knife switch, and the spring is compressed; when the opening operation is executed, the outer cassette type knife switch is separated from the inner cassette type knife switch, and the spring is released. Because the supporting piece is arranged between the two clamping pieces of the external clamping type switch knife, the two clamping pieces of the external clamping type switch knife cannot be extruded and deformed when the spring is released.
The embodiment of the invention also provides a control method of the isolating switch, which is used for controlling the isolating switch.
