Abstract
本实用新型公开了一种变电站接地电阻测试专用放线器，该放线器包括支架（1）、转轴（2）和放线盘（3），支架（1）上安装转轴（2），转轴（2）上安装放线盘（3），导线（4）缠绕放线盘（3）上，整体构成放线器。本实用新型在支架上安装导线紧固器，导线通过紧固器后起到自动紧固的作用，防止导线出现缠绕以及散股的情况，方便现场收线，提高工作效率。
The utility model discloses a special pay-off device for substation grounding resistance test, the pay-off device comprises a support (1), a rotating shaft (2) and a pay-off reel (3), a rotating shaft (2) is installed on the support (1), a rotating shaft (2) A pay-off reel (3) is installed on the top, and the wire (4) is wound on the pay-off reel (3) to form a pay-off as a whole. The utility model installs a wire fastener on the bracket, and the wire can be automatically fastened after the wire passes through the fastener, preventing the wire from being entangled and loose strands, making it convenient to take up the wire on site, and improving work efficiency.
Description
Technical field
The utility model relates to wire dispenser, is specifically related to the special-purpose wire dispenser of substation grounding resistance test.
Background technology
As everyone knows, the substation grounding resistance test need to be arranged wire, and the length of wire is about 4 to 6 times of substation's catercorner length.Take a 110kV substation as example, normally its catercorner length surpasses 200 meters, and test grounding resistance unwrapping wire distance is about 1000 meters.Lighter when finding in the work to put wire, and when receiving wire because drum does not have securing device, wire is loose, the situation that causes wire to lay out drum happens occasionally, again putting wire in order wastes time and energy, and makes troubles to work.
Summary of the invention
The purpose of this utility model is: provide a kind of substation grounding resistance test special-purpose wire dispenser, and simple in structure, easy to carry, processing ease, automatic deploying and retracting and secure wires, time saving and energy saving.
Technical solution of the present utility model is: this wire dispenser comprises support, rotating shaft and draw drum, at support rotating shaft is installed, and draw drum is installed in the rotating shaft, and wire twines on the draw drum, whole formation wire dispenser.
Wherein, in the bottom of support roller is installed.
Wherein, on the top of support pull bar is installed.
Wherein, mounting handle on draw drum.
Wherein, support be positioned at draw drum above turnbuckle is installed, described turnbuckle comprises body, elongated slot and circular hole, the vertical draw drum of body is rack-mount, spaced apart some elongated slots on the lateral wall of body, the bottom of each elongated slot is communicated with circular hole.
Wherein, at the inwall of circular hole protecting jacket is installed.
When unwrapping wire, the wire direct lofting on the pulling draw drum; When take-up, wire is passed circular hole through elongated slot from top to bottom successively, wire is staggered one-in-and-one-out in two adjacent circular holes, by the friction force tension wire of wire and circular hole; According to the quantity that the needs of different conductor fastening force select wire to pass circular hole, the order of selecting different wires to pass through circular hole changes fastening force, passes from minimum circular hole such as penetrating from the highest circular hole directly.
The utlity model has following advantage: 1, conducting wire fastener on support, wire play the effect of automatic fastening after by fastener, prevent that twining from appearring in wire and the situation of broken lot; 2, select wire to pass circular hole quantity and the sequential adjustment fastening force of fastener, convenient on-the-spot take-up is increased work efficiency; 3, at the inwall of circular hole protecting jacket is installed, is prevented the wire damage.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the fastener scheme drawing of Fig. 1.
Among the figure: 1 support, 2 rotating shafts, 3 draw drums, 4 wires, 5 rollers, 6 pull bars, 7 handles, 8 turnbuckles, 9 bodies, 10 elongated slots, 11 circular holes, 12 protecting jackets.
The specific embodiment
As shown in Figure 1, 2, this wire dispenser comprises support 1, rotating shaft 2 and draw drum 3, at support 1 rotating shaft 2 is installed, and draw drum 3 is installed in the rotating shaft 2, and wire 4 twines on the draw drum 3, whole formation wire dispenser.
Wherein, in the bottom of support 1 roller 5 is installed.
Wherein, on the top of support 1 pull bar 6 is installed.
Wherein, mounting handle 7 on draw drum 3.
Wherein, support 1 be positioned at draw drum 3 above turnbuckle 8 is installed, described turnbuckle 8 comprises body 9, elongated slot 10 and circular hole 11, body 9 vertical draw drums 3 are installed on the support 1, spaced apart some elongated slots 10 on the lateral wall of body 9, the bottom of each elongated slot 10 is communicated with circular hole 11.
Wherein, at the inwall of circular hole 11 protecting jacket 12 is installed.
During unwrapping wire, wire 4 direct loftings on the pulling draw drum 3; During take-up, wire 4 is passed circular hole 11 through elongated slot 10, wire is staggered one-in-and-one-out in adjacent two circular holes, by the friction force tension wire of wire 4 with circular hole 11; Select wire to pass circular hole quantity according to different conductor fastening force needs, the order of selecting wire to pass through circular hole changes fastening force, passes from minimum circular hole such as penetrating from the highest circular hole directly.
