Abstract
The invention relates to a cooling device for a secondary over-voltage protector of a current transformer. The cooling device comprises a shell (1), a wiring terminal (2) is arranged on the shell, the cooling device is characterized in that one side of the shell is connected with a reversion extension plate (1a), a plurality of heat dissipation holes (1b) are arranged on the other three side walls of the shell, the reversion extension plate (1a) is connected with a group of wind wheels (3) in an internal rotation matching way, the wind wheels (3) are connected and matched in a transmission manner through a belt (5) and a belt pulley (6), an electric motor (4) is fixedly connected onto the extension plate (7), and an output shaft of the electric motor (4) is connected and matched with the downmost wine wheel (3) in a transmission manner through the belt (5) and the belt pulley (6). The cooling device has the advantages that the cooling effect is good due to the adoption of gas cooling, and meanwhile, a dryer is adopted in the device to remove humidity, so that the secondary over-voltage protector of the current transformer can work normally.
Description
Technical field
The present invention relates to current transformer field, specifically a kind of cooling device of Current Transformer Secondary overvoltage protection device.
Background technology
Existing current transformer (CT) is widely used in electric power system, and it is the requisite kit of ammeter, kilowatt-hour meter and current control system.During normal work, Current Transformer Secondary overvoltage is similar to short-circuit condition, and output voltage is very low.In the situation of actual motion, the secondary winding open circuit if be in operation, or a winding flows through abnormal current, as lightning current, resonance overcurrent, capacitor charging electric current, inductance starting current etc., capital produces the overvoltage of thousands of volts volts even up to ten thousand at secondary side, not only can cause current transformer too drastic and burn, even jeopardize staff's life security, existing Current Transformer Secondary overvoltage protection device, its internal electric source module heating amount is large, continuing in the course of the work large caloric value will cause resistance value to become large, thereby make the temperature rise rate of change of power module sharply increase, and then affected the normal work of Current Transformer Secondary overvoltage protection device, therefore, need a kind of device for cooling electric current transformer secondary overvoltage protector.
Summary of the invention
The object of the invention is the shortcoming existing in prior art in order to solve, and the cooling device of a kind of Current Transformer Secondary overvoltage protection device proposing.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of cooling device of Current Transformer Secondary overvoltage protection device, comprise shell, described shell is provided with binding post, it is characterized in that: a side of described shell is provided with opening, surrounding at opening connects a reversion extension board, the bottom of described reversion extension board is provided with an extension board, on other three sidewalls of described shell, be all provided with a plurality of louvres, in described reversion extension board, be rotatably assorted and connect one group of wind wheel, between described wind wheel by the cooperation that is in transmission connection of belt and belt pulley, on described extension board, be fixedly connected with a motor, on the output shaft of described motor, by belt and belt pulley, be in transmission connection and coordinate with nethermost wind wheel.
On the basis of technique scheme, can there is following further technical scheme:
Described wind wheel comprises a round roller, and the uniform one group of flabellum of surrounding of described round roller, is equipped with a fixed lever at the two ends of described round roller, on the fixed lever of described reversion extension board homonymy, connect corresponding belt pulley.
The invention has the advantages that: this device utilizes gas cooled, good cooling results, this device adopts drier dehumidifying simultaneously, and Current Transformer Secondary overvoltage protection device can normally be worked.
Accompanying drawing explanation
Fig. 1 is basic structure schematic diagram of the present invention.
