Technical field

The utility model belongs to the electrical engineering technical field, relates in particular to a kind of changeable alternating current and galvanic ice melting system.

Background technology

China's southern area ice damage outburst is frequent, makes the broken string of falling the tower phenomenon of grid power transmission circuit particularly heavy, has brought enormous economic loss to power grid enterprises, has had a strong impact on the development and national economy and the people's ordinary production and life simultaneously.

For resisting the ice damage of transmission line, the mature methods that China is used for the transmission line ice-melt at present mainly contains de-icing method and the DC ice melting method of exchanging.These two kinds of methods respectively have its merits and demerits, and its scope of application is also respectively arranged.Transformer station has all only installed a kind of deicing device wherein at present, therefore can only adopt a kind of de-icing method wherein to carry out ice-melt, and the scope of application is narrower.Be the scope of application of raising ice-melt, the choose reasonable de-icing method, how developing a kind of ice melting system that can between alternating current ice-melt and direct current ice-melt, switch is a problem demanding prompt solution.

The utility model content

The technical problem that the utility model will solve is: be directed against the defective that present transformer station alternating current defroster and direct current defroster can't be shared; A kind of changeable alternating current and galvanic ice melting system are provided; This system can switch between alternating current defroster and direct current defroster; To improve the ice-melt ability, satisfy the multiple demand of ice-melt work.

The technical solution of the utility model is; Said changeable alternating current and galvanic ice melting system; As shown in Figure 1, be electrically connected in regular turn and form by alternating current ice-melt switch 1, alternating current defroster 2, direct current output isolator 3, direct current defroster 4, direct current input isolator 5 head and the tail.The input of the output termination alternating current defroster 2 of wherein said alternating current ice-melt switch 1; The output of said alternating current defroster 2 is parallelly connected with the output of direct current output isolator 3; The output of the input termination direct current defroster 4 of said direct current output isolator 3; The output of the input termination direct current input isolator 5 of said direct current defroster 4; And the input of said direct current input isolator 5 is parallelly connected with the input of said alternating current ice-melt switch 1.External 10kV AC power when the line of the input of the input of this direct current input isolator 5 and said alternating current ice-melt switch 1 uses.Connection electric transmission line and it is carried out the alternating current ice-melt or carry out the direct current ice-melt outward when the parallelly connected line of output of the output of above-mentioned alternating current defroster 2 and direct current output isolator 3 uses.

In the said structure of the utility model, the effect of alternating current ice-melt switch 1 is when needing employing alternating current ice-melting mode the direct current defroster to be switched to the alternating current defroster.The effect of alternating current defroster 2 provides the alternating current ice-melting mode transmission line is carried out ice-melt.The effect of direct current defroster 4 provides the direct current ice-melting mode transmission line is carried out ice-melt.The effect of direct current input isolator 5 is isolation of when adopting the direct current ice-melt direct current defroster 4 being imported.The effect of direct current output isolator 3 is the isolation of when adopting the direct current ice-melt direct current defroster 4 being exported.

The beneficial effect of the utility model is:

1), can between direct current defroster and alternating current defroster, switch, applied widely;

2), can be shared a cover 10kV AC power and a transmission line ice-melt disconnecting link, minimizing equipment drops into;

3), simple in structure, small investment, area occupied is little;

4), simple to operate, easy to maintenance.
