Abstract
The utility model discloses a drop out fuse switch with electric volume detects interface. The L-shaped feed-through electric conductor and the feed-through current transformer are arranged at the wiring end part of the load side of the drop-out type fusing switch body, and the secondary side of the feed-through current transformer is used as an electric quantity detection interface. Due to the adoption of the structure, particularly the arrangement of the through current transformer, the data remote measurement of the through current transformer secondary side current acquisition switch and the induction electricity acquisition of the automatic device can be realized. The purpose of the invention is reliably realized. And has the characteristics of simple and practical structure, stable and reliable performance, suitability for industrial popularization and the like.
Description
Technical Field
The utility model relates to a high tension switchgear power supply unit, specifically say so, relate to the high tension switchgear power supply unit who uses for realizing that the circuit segmentation opens and shuts and the protection and the isolation of fault point in the distribution network system.
Background
In the current 10 kV power distribution network power supply system, a drop-out fuse switch is widely applied as a line section switch or a transformer primary side switch, and the protection and isolation of a fault point are realized by overcurrent fuse during power failure or accident of a line through manual pulling and closing operation. With the application of distribution network automation and the input of distributed photovoltaic power supplies in recent years, corresponding switches are required to be provided with an electrical quantity detection interface, and the original drop-out switches cannot meet the requirement of automatic control because the original drop-out switches do not have corresponding functions.
Disclosure of Invention
An object of the utility model is to provide a drop out fuse switch with electric volume detection interface, it can realize being surveyed the electric volume detection of switch, satisfies above-mentioned distribution network system automated control's demand, remedies the not enough of prior art existence.
The technical scheme of the utility model as follows: the drop-out fuse switch comprises an existing drop-out fuse switch body, an L-shaped through conductor and a through current transformer are arranged at the wiring end part of the load side of the drop-out fuse switch body, and the through current transformer is arranged on the through conductor and is realized by taking the secondary side of the through current transformer as an electrical quantity detection interface.
The utility model discloses owing to taken the structure, especially punching current transformer's setting, the data telemetering measurement of accessible punching current transformer secondary side current acquisition switch and automatic device's response are got the electricity. The purpose of the invention is reliably realized. And has the characteristics of simple and practical structure, stable and reliable performance, suitability for industrial popularization and the like.

Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
As shown in fig. 1, the drop-out fuse switch with an electrical quantity detection interface of the present invention is a novel switch designed on the basis of the existing drop-out fuse switch. An L-shaped through conductor 2 is fixed at the end part of a load side wiring of the existing drop-out fuse switch body 1, a through current transformer 3 is arranged on the through conductor 2, and a wiring terminal in a sealable wiring terminal cover on the secondary side of the through current transformer 3 is used as an electrical quantity detection interface 4.
In order to adapt to the operation environment of the conventional drop-out fuse switch, the feed-through current transformer 3 and the secondary lead wire operate in an equipotential mode, and the secondary lead wire and an automatic device matched with the secondary lead wire operate in an equipotential state of being insulated to the ground. The automatic device and the conventional drop-out fuse switch have the same operation condition, and the voltage resistance and insulation problems do not need to be specially solved, so that the automatic device is more convenient to use.
When the through current transformer is used, when current passes through the through current transformer 3, corresponding induced current output exists in a secondary winding of the through current transformer, the output quantity of the secondary winding can be used as a telemetering acquisition signal of the switch to be used for monitoring and controlling a distribution network automation system, counting electric quantity, controlling equipment and the like, meanwhile, the output current of the secondary winding can also provide a working power supply for an automatic device installed at the position in an induction power taking mode, and the through current transformer can also adopt different transformation ratios and multi-winding modes to facilitate field selection and application.
