Abstract
The utility model relates to an electric power fitting, particularly a wire clamp for a switching special device, which can directly realize the distribution or the reliable connection of the conductive rod of the oil switch on a pole and an extraction directing line. The wire clamp for a switching special device makes the conductive rod of the device and the directing line which is to be externally connected become integration through connecting. Through a locking bolt and a compacting bolt, the conductive rod and the externally guiding directing line are reliably fixed onto the both ends of the wire clamp for a switching special device. The utility model has the advantages of convenient arrangement, large conducting contact area, tight connection, small resistance, and good universal performance. The wire clamp for a switching special device which can solve the oil seepage problem generated by the ageing of the rubber bead caused by the large distribution secondary current and the exothermic contact point of the conductive rod is suitable for all kinds of distributions, the oil switch on the pole, etc.
Description
The utility model belongs to a kind of electric armour clamp, exactly is a kind of distribution special equipment wire clamp.
At present controller switching equipment does not have the specialized apparatus wire clamp, and the conducting rod of distribution oil switch and being connected of lead on general distribution transformer and the post all use the converting equipment wire clamp, adopt copper-aluminium transition equipment cable clamp usually.At terminal sidetracking one circular hole of wire clamp, distribution transforming or the post switches conductive bar that oils is inserted in the circular hole, with the fastening binding post that compresses wire clamp up and down of two nuts on the conducting rod.The shortcoming of this connected mode is: effectively contact area is little, has only the contact area of annulus area and the nut and the conducting rod screw thread of clamp nut.Because operating current is big, contact area is little, and the terminal problems of excessive heat often takes place, and long-time overheatedly makes the sealant bead on the distribution transformer secondary sleeve pipe aging, thereby causes seepage oil.But the serious rubescent secondary sleeve pipe that burns of overheated distribution transforming secondary conducting rod makes oil switch generation phase fault on the 10KV post, damages switch, causes line tripping.This big situation of device clamp incompatibility controller switching equipment voltage low current that substitutes influences safe power supply.
It is a kind of easy for installation that the purpose of this utility model is to provide, and contact area is big, and contact is closely reliable, adapts to the distribution special equipment wire clamp of distribution low-voltage, big electric current characteristics.Fundamentally solve because of electric current is big, contact area causes for a short time generating heat and produces seepage or burn out binding post and the problem of equipment.Improve the power supply reliability of controller switching equipment, reduce the controller switching equipment breakthrough.
The technical solution of the utility model is achieved in that distribution special equipment wire clamp presss from both sides two parts by appliance terminal and wire connecting line and forms as a whole.Appliance terminal comprises the Luo hole and locks the Luo bolt and be connected the Luo hole; The wire connecting line folder comprises gland, Luo hole and compresses the Luo bolt and the lead fixed groove.Appliance terminal is screwed on the conductor rod of oil switch on Allocation transformer transformer or the post by connecting the Luo hole, tightens locking Luo bolt then, the conductor rod of oil switch on appliance terminal and Allocation transformer transformer or the post closely is connected.Will draw lead insert in the lead fixed groove of wire connecting line folder, tighten and compress the Luo bolt on the gland, make and draw lead and be firmly fastened in wire clamp.
The utility model compared with prior art has easy for installationly, and contact area is big, connects closely, and resistance is little, and is safe and reliable, different size can with beneficial effect such as the supporting use of oil switch on the distribution transformer of different capabilities or the post.
Accompanying drawing 1 is the structure chart of distribution special equipment wire clamp.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Distribution special equipment wire clamp presss from both sides 1 two parts by appliance terminal 2 and wire connecting line to be formed as a whole.Appliance terminal 2 comprises Luo hole 9, locking Luo bolt 5 and is connected Luo hole 6; Wire connecting line folder 1 comprises gland 3, Luo hole 8, compresses Luo bolt 4 and lead fixed groove 7.According to the diameter of controller switching equipment conductor rod, select suitable distribution special equipment wire clamp.Take off original mother Luo on the equipment conductor rod, conductor rod is screwed in the connection Luo hole 6 on appliance terminal 2 of distribution special equipment wire clamp, tighten locking Luo bolt 5 again, equipment splicing ear 2 is securely fixed on the conductor rod.Unclamp then and compress Luo bolt 4 on the wire connecting line folder 1, will draw lead and insert in the lead fixed groove 7, evenly tighten and compress Luo bolt 4, make and draw lead and be securely fixed on the wire connecting line folder 1.
