Abstract
The utility model discloses a loop transfer isolating switch in an indoor electric power distribution network of 12kv; the main body of the switch is fixed on an underframe (5) with the sun pattern of the switch by three groups of isolators (2), (6); two connection terminals (1) which need to transfer a power supply loop are respectively arranged on the two outer isolators (2); a power output connection terminal (8) is fixed on the middle isolator (6); two rotating shafts (4) are fixed on the underframe (5); the two rotating shafts (4) are respectively connected by a tension rod (3) and two loop contact knifes (7); the rotating shafts (4) rotate to drive the contact knifes (7) to rotate, so as to switch on and off a strobe; the loops are realized to be transferred by controlling the rotating sequence of the two rotating shafts (4) arranged on the underframe (5). The loop transfer isolating switch has the advantages of compact structure, little material consumption and light weight; besides, the integral occupied space is small.
Description
Technical field
The utility model relates to a kind of isolating switch, and is relevant with the loop switching isolating switch in a kind of indoor 12kV distribution system especially, belongs to electrical technology field.
Background technology
In the electric power power transmission and transforming equipment, high voltage isolator be realize deciliter, the visual plant of conversion line and assurance interruption maintenance safety.Indoors in the 12kV distribution system, some important electric equipment need have two current supply circuits, and one of them loop is used for using when the interruption maintenance of another loop.Switching between two loops so just needs two isolating switches.But two isolating switches take up room greatly, and the material consumption is many, have brought great inconvenience for especially the manufacturing of supporting cabinet.
Summary of the invention
The purpose of this utility model is that isolating switch is switched in the loop that volume is little, consumptive material is few of using in a kind of indoor 12kV of design system.
Technical solutions of the utility model are such: switch main body is fixed on the switch day shape underframe by three groups of insulators.The binding post of two need switching current supply circuits is installed in respectively on two outside insulators, and output electric energy binding post is fixed on the intermediate standoff.Be fixed with two rotating shafts on the underframe, two rotating shafts are connected with two loop contact knifes with pull bar respectively.
Isolating switch is switched in the loop that the utility model provides, and rotating shaft rotating band movable touch knife rotates realizes the switch on/off switch.By the rotation sequencing of two rotating shafts on the control underframe, can reach the purpose of switching circuit.Compact conformation, integral body takes up room little, and consumptive material is few, in light weight.
Description of drawings
Fig. 1 is the structural representation of existing two isolating switch switching circuits;
Fig. 2 switches the structural representation of an embodiment of isolating switch for the utility model loop.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, switching circuit binding post 2, outside insulator 3, pull bar 4, rotating shaft 5, day shape underframe 6, intermediate standoff 7, contact knife 8, outlet side binding post
In the embodiment shown in Figure 2, switch main body is fixed on the switch day shape underframe 5 by three groups of insulators 2,6.The binding post 1 of two need switching current supply circuits is installed in respectively on two outside insulators 2, and output electric energy binding post 8 is fixed on the intermediate standoff 6.Being fixed with two rotating shafts, 4, two rotating shafts 4 on the underframe 5 is connected with two loop contact knifes 7 with pull bar 3 respectively.7 rotations of rotating shaft 4 rotating band movable touch knifes come on/off switch.By the sequencing of two rotating shafts, 4 rotations on the control underframe 5, to reach the purpose of switching circuit.
