Furthermore, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Referring to fig. 3 to 13, an embodiment of the present invention provides an integrated intelligent protection system applied to distribution automation, which is formed by performing field transformation on an existing ring main unit and assembling a DTU intelligent terminal, and is convenient and simple in equipment transformation and flexible and quick in installation process.
The comprehensive intelligent protection system comprises a power transmission and distribution electrical unit 200, a DTU intelligent terminal 300 and an installation unit 100 for externally hanging the DTU intelligent terminal 300 on the power transmission and distribution electrical unit 200.
The mounting unit 100 includes a fixing plate 101, a bearing 102 having one end hinged to the fixing plate 101 and the other end capable of relative rotation, and a support member 103 detachably coupled between the fixing plate 101 and the bearing 102. The fixing plate 101 is used for connecting and fixing the side wall of the DTU intelligent terminal 300 and the side wall of the transmission and distribution electric unit 200; the supporting member 102 is used for supporting the bottom of the DTU intelligent terminal 300, and may be a plate-shaped structure or a plurality of rod-shaped structures arranged at intervals; the support member 103 serves to keep the structure of the susceptor 102 stable.
The two ends of the supporting member 103 are detachably connected to the fixing plate 101 and the supporting member 102, respectively, and can form a triangular stable structure, and when the triangular stable structure is formed, the supporting member 102 extends outwards in the horizontal direction.
The transmission and distribution electric unit 200 includes an opening and closing station box 201 and a ring main unit disposed inside the opening and closing station box 201, and the fixing plate 101 is attached and fixed to an outer side wall of the opening and closing station box 201 and can be fixed by penetrating a bolt.
The DTU intelligent terminal 300 is placed on the supporting piece 102 and is electrically connected with the ring main unit inside the switching station box 201; in the invention, threading holes C corresponding to each other are respectively arranged on the side wall of the DTU intelligent terminal 300, the side wall of the switching station box body 201 and the fixing plate 101 and are used for penetrating wires connected between the DTU intelligent terminal 300 and the ring main unit.
Based on the above, DTU intelligent terminal 300 can install fast on the outer wall of transmission and distribution electrical unit 200 to circuit transformation and electric connection, and installation transformation process convenient and fast.
Further, the supporting member 102 is of a plurality of rod-shaped structures arranged at intervals, and specifically, the supporting member 102 includes a plurality of supporting rods 102a hinged to the fixing plate 101 one by one, and engaging rods 102b integrally engaging outer ends of the supporting rods 102a in a transverse direction.
One end of the support member 103 is detachably connected to the fixing plate 101, and the other end is detachably connected to the coupling rod 102b, and a triangular stable structure can be formed.
The hinge point of the supporting member 102 and the fixing plate 101 is set as a hinge point. The outer end of the supporting part 103 can be connected with the joint rod 102b, and the inner end can be fixed on the upper part of the hinge point and also can be fixed on the lower part of the hinge point, and the two fixing modes can form a triangular stable structure:
when the inner end of the supporting member 103 is fixed on the upper portion of the hinge point, the supporting member 103 has a function of pulling in a diagonal direction, receives a pulling force, and can prevent the supporting member 103 from turning downwards and falling by pulling the overhanging supporting member 102. When the inner end of the supporting member 103 is fixed at the upper portion of the hinge point, the supporting member 103 is preferably connected at both sides of the fixing plate 101, preventing the collision and influence of the resting installation stroke structure of the DTU smart terminal 300.
When the inner end of the supporting member 103 is fixed at the lower part of the hinge point, the supporting member 103 has a function of pressing and propping, is pressed, and can prevent the overhanging supporting member 102 from overturning downwards and falling. When the inner end of the supporting member 103 is fixed to the lower portion of the hinge point, the supporting member 103 may be arranged in plural numbers at the lower portion of the supporting member 103 to improve the stability and pressure resistance of the structure.
Further, the fixing plate 101 is formed with receiving grooves 101a corresponding to the respective support rods 102a, and the receiving grooves 101a are arranged at intervals such that the fixing plate 101 forms a periodic concave-convex structure.
One end of each of the support rods 102a is hinged to the bottom of the corresponding receiving groove 101a (i.e., the hinge point is located at the bottom of the receiving groove 101a), and can be rotatably fitted into the receiving groove 101 a. Therefore, the housing groove 101a of the present invention has two functions: firstly, the fixing plate 101 forms a periodic concave-convex structure, so that the structural strength and the disturbance resistance of the fixing plate 101 can be enhanced; and each accommodating groove 101a can accommodate a corresponding bearing rod 102a, so that the space can be saved when the mounting unit 100 is transported or carried, and the bearing rods can be directly stacked layer by layer when being stocked.
Preferably, the upper end of the receiving groove 101a is through, and the length of the receiving groove 101a is not greater than the length of the supporting rod 102a, so that after the supporting rod 102a is rotatably inserted into the receiving groove 101a, the transverse engaging rod 102b can be just fastened on the top of the fixing plate 101, thereby ensuring the complete insertion and receiving of the supporting rod 102 a.
Further, the cross section of the joint rod 102b is circular, and the outer diameter of any cross section of the joint rod 102b is the same and is larger than the thickness of the bearing rod 102 a.
The supporting members 103 may be provided with a plurality of members having the same size, and include a rod 103a, a snap ring 103b fixed to one end of the rod 103a, and a connector 103c fixed to the other end of the rod 103 a.
The inner part of the clamping ring 103b is provided with a bayonet 103b-1 matched with the outer diameter of the connecting rod 102b, the outer edge of the clamping ring 103b is provided with a notch 103b-2 communicated with the bayonet 103b-1, and the minimum distance between the notches 103b-2 is smaller than the outer diameter of the connecting rod 102b and larger than the thickness of the bearing rod 102 a; the snap ring 103b can be sleeved on the joint rod 102b through the bayonet 103 b-1. When the notch 103b-2 faces the length direction of the bearing rod 102a inwards, the snap ring 103b sleeved on the connecting rod 102b can slide along the length direction of the connecting rod 102b to adjust the transverse position (the notch 103b-2 can avoid the influence of the bearing rod 102a on the stroke of the snap ring 103b in the sliding process, and cannot cause the snap ring 103b to be separated from the connecting rod 102 b.
The outer end of the connector 103c is provided with a U-shaped opening 103c-1 with an outward opening, and a U-shaped fixing buckle 103c-2 is rotatably arranged in the U-shaped opening 103 c-1. The outer peripheral contour of the U-shaped retaining buckle 103c-2 fits the inner contour of the U-shaped opening 103c-1, can be nested in the U-shaped opening 103c-1, and can be rotated out of the U-shaped opening 103 c-1.
The U-shaped fixing buckle 103c-2 includes a semicircular ring 103c-21 and connecting ends 103c-22 integrally formed at both ends of the semicircular ring 103 c-21. The U-shaped fixing buckle 103c-2 is hinged with a pair of rotating shafts 103c-11 in the U-shaped opening 103c-1 one by one through two connecting ends 103c-22, and can rotate into or out of the U-shaped opening 103c-1 around the rotating shafts 103 c-11. As shown in FIG. 10, when the U-shaped fastener 103c-2 is rotated into the U-shaped opening 103c-1, the inner sidewall of the U-shaped fastener 103c-2 forms an outwardly opening locking opening K; when the U-shaped fixing buckle 103c-2 is rotated out of the U-shaped opening 103c-1, the inner side wall of the U-shaped fixing buckle 103c-2 and the U-shaped opening 103c-1 can jointly enclose a closed locking hole S.
The fixing plate 101 is symmetrically provided at both sides thereof with hooking shafts 101b fitted to the outer diameters of the semicircular rings 103c-21 corresponding to the locking holes S. When the U-shaped fixing buckle 103c-2 is rotated out of the U-shaped opening 103c-1, the formed locking hole S can be sleeved on the hook hanging shaft 101b to form pulling fixation.
A pressing shaft 101c extending in the width direction (lateral direction) of the fixing plate 101 and fitted to the outer diameter of the semicircular rings 103c to 21 is fixed to the lower end of the fixing plate 101 corresponding to the locking opening K (the pressing shaft 101c may be fixed to the bottom of the fixing plate 101 by a connecting post 101 d). When the U-shaped fixing buckle 103c-2 is rotated into the U-shaped opening 103c-1, the formed locking opening K can be clamped on the hook hanging shaft 101b to form extrusion fixing. Preferably, the pressure shaft 101c is provided with an annular groove 101c-1 corresponding to the locking opening K, and the U-shaped fixing buckle 103c-2 can be engaged in the annular groove 101c-1 through the locking opening K to prevent lateral sliding.
If the hinge point of the support member 102 and the fixing plate 101 is used as a hinge point, the hooking shaft 101b is located at the upper portion of the hinge point, and the pressure-receiving shaft 101c is located at the lower portion of the hinge point.
Further, a U-shaped limit plate 103c-12 having the same contour as the U-shaped fixing buckle 103c-2 is disposed inside the U-shaped opening 103c-1, the thickness of the U-shaped limit plate 103c-12 is smaller than the thickness of the connector 103c, and an accommodating space is formed at one side of the U-shaped limit plate 103c-12, the U-shaped fixing buckle 103c-2 can rotate into or out of the accommodating space around the rotating shaft 103c-11, and when the U-shaped fixing buckle 103c-2 rotates into the accommodating space, the contour of the inner side wall of the U-shaped fixing buckle 103c-2 can be consistent with the contour of the inner side wall of the U-shaped limit plate 103c-12, so as to form a U-shaped locking opening K together.
Further, the outer end of the hooking shaft 101b is provided with a threaded section 101 b-1. When the U-shaped fixing buckle 103c-2 is rotated out of the U-shaped opening 103c-1 and sleeved on the hook shaft 101b, the threaded section 101b-1 at the outer end of the hook shaft 101b can be connected with the limit nut 101b-2, and the connector 103c is prevented from being separated from the lateral direction through the lateral limit of the limit nut 101 b-2.
Meanwhile, screw holes 102b-1 are formed in two ends of the connecting rod 102b, and limit bolts 102b-2 can be connected into the screw holes 102b-1 to form lateral limit on the clamp ring 103 b.
Based on the above, as shown in fig. 7, when the volume of the DTU smart terminal 300 is small, the support members 103 may be disposed on both sides of the fixing plate 101 to be used as diagonal members, that is: the snap ring 103b is fitted over the engaging rod 102b, and the U-shaped fixing buckle 103c-2 at the upper end is rotated out of the U-shaped opening 103c-1 and fitted over the hooking shaft 101b through the formed locking hole S.
As shown in fig. 8, when the volume of the DTU intelligent terminal 300 is large (when the width of the DTU intelligent terminal 300 is larger than the lateral width of the support 102), if the support member 103 is still disposed on both sides of the fixing plate 101, the DTU intelligent terminal 300 will be prevented from resting on the support 102, and therefore, the support member 103 can be disposed at the bottom of the support 102 to be used as a compression bar, that is: the snap ring 103b is fitted over the engaging rod 102b, and the U-shaped holder 103c-2 at the lower end is rotated into the U-shaped opening 103c-1 and is snapped onto the pressure receiving shaft 101c through the formed locking opening K.
Of course, as shown in fig. 9, the present invention may also be configured with supporting members 103 on both sides of the fixing plate 101 and at the bottom of the supporting member 102, and the supporting members are combined with diagonal tension rods and compression rods to enhance the strength of the structure.
Furthermore, at least a part of the supporting rod 102a is hinged with a turning plate 104 on the bottom surface, and the rotation axis of the turning plate 104 is parallel to the length direction of the supporting rod 102 a.
When the support rod 102a is inserted into the receiving groove 101a, the flap 104 can also be turned over in the lateral direction and attached to the outer surface of the fixing plate 101, thereby occupying no space.
When the support rod 102a is rotated outward to be perpendicular to the fixing plate 101 and the flap 104 is turned to be perpendicular to the support rod 102a, the inner edge of the support rod 102a can contact the outer surface of the fixing plate 101.
In the invention, when the support rod 102a rotates outwards to be vertical to the fixed plate 101, the turning plate 104 can naturally turn over and hang down due to the edge of the self-weight and lean against the outer surface of the fixed plate 101 to form the function of a stiffening rib, so that the compressive strength of the support rod 102a is enhanced.
Further, a reinforcing plate 105 is provided on the inner side wall of the switching station case 201. Wherein, reinforcing plate 105, the lateral wall of switching station box 201, fixed plate 101 and the 300 lateral walls of DTU intelligent terminal hug closely in proper order to pierce through fixedly through fastening bolt 106, and at this moment, threading hole C on the 300 lateral walls of DTU intelligent terminal, on the 201 lateral wall of switching station box and on the fixed plate 101 can just right each other, guarantee penetrating.
Further, based on the above technical solution, the DTU intelligent terminal 300 can be quickly fixed on the outer wall of the transmission and distribution electrical unit 200, and in addition, the internal circuits of the DTU intelligent terminal and the transmission and distribution electrical unit need to be connected.
