Automatic short-circuit air plug

Abstract

The invention discloses an automatic short-circuit air plug, and relates to the technical field of a power distribution network. The automatic short-circuit air plug comprises a first insertion core and a second insertion core, wherein at least two rows of first insertion pieces are arranged on the first insertion core, at least two rows of second insertion pieces are arranged on the second insertion core, the automatic short-circuit air plug has a combination state and a split state, the first insertion core is provided with an automatic short-circuit mechanism, the second insertion core is provided with a cutoff mechanism, in the split state, at least one pair of first insertion pieces in adjacent two rows are short-connected by the automatic short-circuit mechanism, in the combination state, the contact of the automatic short-circuit mechanism and the first insertion pieces is cut off by the cutoff mechanism, and the first insertion pieces and the second insertion pieces are conducted with each other. The automatic short-circuit air plug has an automatic short-circuit function, the labor intensity is reduced, and the safety coefficient and the working efficiency of site installation and maintenance are substantially improved.

Description

【Technical field】 [0001] The invention relates to the technical field of power distribution network, in particular to a self-short-circuit aerial plug. 【Background technique】 [0002] With the rapid development of the economy, the demand for electricity continues to expand, and the operation and maintenance requirements of power companies are also getting higher and higher. The maintenance of the distribution network system of 10kV and below is becoming more and more important. The scientific, reliable and accurate operation of the distribution system is becoming more and more important. It is an important work content for the power grid to ensure safe production. In the existing technology, for the distribution network system of 10kV and below, the transformation and protection replacement of the ring main unit needs to operate the terminal block, connect the cables to the secondary circuit, and install the primary and secondary circuits of the power distribution system.

Problems solved by technology

In the existing technology, for the distribution network system of 10kV and below, the transformation and protection replacement of the ring main unit needs to operate the terminal block, connect the cables to the secondary circuit, and install the primary and secondary circuits of the power distribution system. For the test work, if the secondary circuit is a live operation, it is necessary to manually move the current metal slide of the terminal for safety measures and other work. Since the terminal metal of the secondary circuit is exposed, the on-site operation is complicated, the steps are cumbersome, and the human factors are large. Work efficiency Low, so it is prone to safety accidents such as human accidental contact, short circuit of voltage transformer caused by miswiring, open circuit of current transformer, outage of low-voltage cabinet and ring network cabinet in substation, etc.
