Description
Technical field
This utility model relates to power transmission security technology area, and a kind of durable type that can remotely monitor is taken shelter from the thunder
Device.
Background technology
Metal oxide arrester (MOA) is in parallel with distribution transforming when normal work, upper end link, lower end ground connection.Work as line
When there is overvoltage in road, three parts that distribution transforming now will produce when bearing overvoltage by spark gap, lead-in wire and grounding device
Pressure drop, referred to as residual voltage.In this three parts overvoltage, the residual voltage on spark gap is relevant with himself performance, and its residual voltage value is one
Fixed.Residual voltage on grounding device can be connected to distribution transforming shell by making down conductor, is connected with grounding device the most again
Mode is eliminated.To the key point just becoming protection distribution transforming with the residual voltage how reduced on lead-in wire.The impedance of lead-in wire is with logical
The power frequency crossed is relevant, and frequency is the highest, and the inductance of wire is the strongest, and impedance is the biggest.Knowable to U=IR, on lead-in wire to be reduced
Residual voltage, must reduce lead impedance, and the feasible method reducing lead impedance is to shorten the MOA distance away from distribution transforming, draws to reduce
Line impedence, reduce lead-in wire pressure drop, so spark gap should be arranged on distance distribution transformer near point more suitable.If distribution low-voltage side
Being fitted without MOA, when high-pressure side spark gap releases lightning current to the earth, just produce pressure drop on grounding device, this pressure drop is led to
Cross distribution transforming shell to act simultaneously at the neutral point of low-pressure side winding.Therefore the lightning current flow through in low-pressure side winding will make high pressure
Side winding induces the highest electromotive force (up to 1000kV) by no-load voltage ratio, and this electromotive force, by superposing with the lightning voltage of high-pressure side winding, is made
Become high-pressure side winding neutral point potential to raise, puncture the insulation near neutral point.If low-pressure side is mounted with MOA, work as high-pressure side
MOA electric discharge is when making the current potential of grounding device be increased to certain value, and low-pressure side MOA starts electric discharge, make low-pressure side winding terminal with
The potential difference of its neutral point and shell reduces, and thus can eliminate or reduce the impact of " inverse transformation " electromotive force.Existing spark gap
Overhauling loaded down with trivial details, moisture preventive measure imperfection causes spark gap not work, and spark gap is short for service life, easily causes spark gap and damages
Normally cannot be worked the problem that can not find in time, for this it is proposed that the remote controlled durable type spark gap of a kind of electric power.
Utility model content
