Abstract
The invention relates to a cooling apparatus for a current transformer secondary overvoltage protection device. The apparatus comprises a housing (1). The housing (1) is provided with a wiring terminal (2). The apparatus is characterized in that the two symmetrical shells of the housing are each provided with a pipeline interface (1a), one of the pipeline interfaces (1a) is connected with an air-supply pipe (3), the other pipeline interface (1a) is connected with an air-discharge pipe (6), and the air-supply pipe (3) is connected with a cooling gas source (5). The advantages of the apparatus are as follows: gases are utilized for cooling, the cooling effect is good, at the same time, the apparatus employs a dryer for dehumidification, and the current transformer secondary overvoltage protection device is enabled to work normally.
Description
Technical field
The present invention relates to current transformer field, specifically a kind of heat sink for 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.When 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 affect 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 a kind of heat sink for Current Transformer Secondary overvoltage protection device proposing.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of heat sink for Current Transformer Secondary overvoltage protection device; comprise shell 1; described shell 1 is provided with binding post 2; it is characterized in that: on two symmetrical housings of described shell 1, be respectively equipped with a pipe joint 1a; pipe joint 1a described in one of them connects blast pipe 3, another pipe joint 1a connects discharge pipe 6, and described blast pipe 3 connects cooling source of the gas 5.
On the basis of technique scheme, can there is following further technical scheme:
On described blast pipe 3, also connect a drier 4.
Described shell 1 is a gastight housing of sealing.
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.
Brief description of the drawings
Fig. 1 is basic structure schematic diagram of the present invention.
