Description
Technical field
What the present invention proposed is a kind of transmission line post insulator of field of power transmission.
Background technology
Transmission line pillar is used to the parts supporting transmission line, and existing electric transmission line isolator is generally the Body of pillar of pottery, plays a supporting role to the electric wire of circuit, does not have other function.But electric transmission line isolator not only can produce supporting role to electric wire, can also carry out information understanding to the running status of circuit, therefore, existing electric transmission line isolator can not meet technical requirement.
Summary of the invention
In order to realize transmission line monitoring running state, the invention provides a kind of transmission line post insulator.This insulator, by arranging monitor box on the insulator, solves the technical problem of electric transmission line isolator and power transmission state monitoring.
The scheme that technical solution problem of the present invention adopts is: outside pillar, be set with insulator, is provided with monitor box outside the pillar on superincumbent insulator.Low-voltage circuit and high-tension circuit is provided with in monitor box.
Good effect, because the present invention arranges electronic circuit on electric transmission line isolator, for monitoring Research Work of Power Transmission Line state.So, adopt post insulator of the present invention can understand in real time and monitoring transmission line running status.Be suitable for applying as transmission line post insulator.
