Abstract
The invention relates to a mutual inductor field calibration wire-connection method which is characterized of comprising the following steps. Step 1, connect one connector lug of a calibration instrument to terminals of a ground rod, step 2, hang the ground rod on a primary bus of a mutual inductor to calibrate the mutual inductor. According to the mutual inductor field calibration wire-connection method, the ground rod has a certain length, so that a staff has no need to climb to positions equipped with the mutual inductor and avoids personal risk for high-position work when installing the ground rod on the primary bus of the mutual inductor. Besides, a mutual inductor primary device is prevented from damage, the security of the mutual inductor field calibration is effectively improved, and the efficiency of calibration work is enhanced.
Description
Technical field
The invention belongs to the electric power overhaul technical field, particularly a kind of mutual inductor on site verification mode of connection.
Background technology
During field-checking, the work people need climb up framework and mutual inductor when disconnecting primary line, and bus of primary connection wire clamp and mutual inductor of tester is connected.Due to mutual inductor top and around the fixing place of securing band not, so securing band can only be enclosed within on mutual inductor, there are potential safety hazard in staff's the person and equipment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of handling safety is provided, avoid ascend operation, the mutual inductor on site verification mode of connection that the protection primary equipment is not damaged.
The present invention solves its technical matters and takes following technical scheme to realize:
A kind of mutual inductor on site verification mode of connection is characterized in that: comprise the following steps:
⑴, the primary connection head of tester is connected to the terminals of ground rod;
⑵, ground rod is mounted on bus of mutual inductor, mutual inductor is carried out verification.
Advantage of the present invention and good effect are:
Mutual inductor on site verification mode of connection of the present invention, because ground rod has certain-length, when being mounted to ground rod on bus of mutual inductor, the staff need not to seek connections with in the mutual inductor position, has avoided the Personal Risk who operating personnel is produced because of ascend operation; Simultaneously, avoid damage to the mutual inductor primary equipment; Effectively improve the security of transducer check site work, improve the efficient of verifying work.
Embodiment
The invention will be further described below by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of mutual inductor on site verification mode of connection is characterized in that: comprise the following steps:
⑴, the primary connection wire clamp that at first will have tester now are pulled down, and pull down simultaneously the ground wire of existing ground rod, are responsible for the primary connection head of tester is connected to the terminals of ground rod by the specific responsibility personnel; And check whether the junction is firm.
⑵, ground rod is mounted on bus of mutual inductor, then mutual inductor is carried out verification.
Principle of work of the present invention is:
Because ground rod has certain-length, when being mounted to ground rod on bus of mutual inductor, the staff need not to seek connections with in the mutual inductor position, has avoided the Personal Risk who operating personnel is produced because of ascend operation; Simultaneously, avoid damage to the mutual inductor primary equipment; Effectively improve the security of transducer check site work, improve the efficient of verifying work.
Although disclose for the purpose of illustration embodiments of the invention, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the present invention and claims, various replacements, variation and modification are all possible, therefore, scope of the present invention is not limited to the disclosed content of embodiment.
Claims (1)
1. mutual inductor on site verification mode of connection is characterized in that: comprise the following steps:
