The utility model provides a converter adopting a heat pipe to self cool and radiate. The converter comprises a power cabinet body, an air inlet which is arranged below the cabinet body, an air outlet which is arranged on the top portion, and a plurality of heat pipe radiators, a plurality of capacitance assemblies and a plurality of power assemblies which are arranged in the cabinet body. The converter is characterized in that the heat pipe radiators are arranged on the upper portion of the cabinet body in rows, the power assemblies are arranged below the cooling base boards of the radiators in parallel, the capacitance assemblies are arranged below the power assemblies, and the capacitance assemblies are connected with the power assemblies through busbars. Heat is discharged to the outside of the cabinet body through operating principles of the heat pipe in a radiating process of the converter, heat exchange is achieved, and the power assemblies can achieve good isothermal performance, be free of temperature overlapping states and achieve high-quality radiating due to the fact that the power assemblies are arranged inside the cabinet body in parallel and the radiators are installed in a same plane in rows.

Description

A kind of current transformer that adopts the heat pipe self-cold radiating
Technical field
The utility model belongs to wind power generation field, relates to a kind of converter structure design, is a kind of converter structure design of adopting heat pipe self-cold radiating mode specifically.
Background technology
Current transformer carries out excitation through the rotor to dual-feed asynchronous wind power generator, makes that stator side output voltage amplitude, frequency and the phase place of double-fed generator are identical with line voltage, and can gain merit as required and idle independent decoupling zero control.The main radiating mode of current transformer has air-cooled and two kinds of radiating modes of water-cooled.Water-cooling heat radiating system is to come heat conduction through recirculated water, mainly is made up of several parts such as heat exchanger, the circulatory system, water tank, water pump and water.Water-cooling system has excellent heat dispersion, but its complex structure and leakage easily are very high to installation requirement.Air cooling system mainly is through fan and fin heat to be reached surrounding environment.Air cooling system has simple in structure, and is cheap, safe and reliable, and characteristics such as technology maturation are the main radiating modes that small-sized wind electric converter adopts.
The current transformer pyrotoxin is an IGBT power device in the power cabinet; Tradition current transformer power cabinet arrangement is as shown in Figure 1: net side and pusher side power cell are fixed on the cabinet inner radiator; Capacitance component is placed between net side and the pusher side power cell, and capacitance component, net side power cell and pusher side power cell connect through laminated bus bar each other.Air inlet is placed the cabinet front-side underside, and air outlet places above the cabinet, and fan places radiator bottom.The air channel just need be passed from cabinet like this, then heat is sent to the cabinet outside.The drawback of this kind cabinet body structure design is that the air channel needs tight cooperation, and the upper strata (PCC) power receives the influence of lower floor's (PCC) power, and in same plane, the upper component temperature must be higher than the temperature of lower floor (PCC) power; Dust process in the cabinet can be brought a large amount of dusts, if untimely cleaning must impact components and parts in the cabinet on the other hand.
Summary of the invention
The utility model proposes a kind of current transformer that adopts the heat pipe self-cold radiating.Heat is discharged from the cabinet outside through the operation principle of heat pipe, realizes the exchange of heat, thereby reaches self-cold radiating, its good heat dissipation effect.
Said a kind of current transformer of heat pipe self-cold radiating that adopts comprises the power cabinet cabinet; Below cabinet, be provided with air inlet, the top is provided with air outlet, in cabinet, is provided with a plurality of heat-pipe radiators, capacitance component and (PCC) power; It is characterized in that: said heat-pipe radiator is set in row on cabinet top; The (PCC) power parallel connection is arranged on the cooling base below of radiator, and capacitance component is arranged on the below of (PCC) power, and is connected with (PCC) power through composite bus bar.
Said air inlet is positioned at the preceding side lower part of cabinet.
Two rows before and after said heat-pipe radiator has, three of every rows.
Heat is discharged from the cabinet outside through the operation principle of heat pipe in the utility model heat radiation process, realizes the exchange of heat, thereby reaches self-cold radiating, its rapid heat dissipation, good heat dissipation effect.Owing in the process that heat is extracted, do not exist the traditional heat-dissipating device to rely on the characteristics of blower fan air draft, therefore, can keep higher IP grade in the cabinet.

Embodiment
To combine the accompanying drawing in the utility model below, the utility model will be done to carry out clear, intactly description.Like Fig. 2, shown in 3; Said a kind of current transformer of heat pipe self-cold radiating that adopts comprises power cabinet cabinet 1; Below cabinet 1, be provided with air inlet 7, the top is provided with air outlet 8, in cabinet 1, is provided with a plurality of heat-pipe radiator 2, capacitance component 6 and (PCC) power 4; It is characterized in that: said heat-pipe radiator 2 is set in row on cabinet 1 top; (PCC) power 4 parallel connections are arranged on cooling base 3 belows of radiator 2, and capacitance component 6 is arranged on the below of (PCC) power 4, and are connected with (PCC) power 4 through composite bus bar 5.
Said air inlet 7 is positioned at the preceding side lower part of cabinet.
Two rows before and after said heat-pipe radiator 2 has, three of every rows.
The (PCC) power of the utility model produces a large amount of heats (Fig. 4, Fig. 5) when work, the cooling base 3 that is installed in heat pipe 2-1 bottom at first obtains these heats, through the inner working media of heat pipe 2-1; Conduct to the top of heat pipe 2-1, heat pipe 2-1 is through the function of its quick exchange heat, heat transferred radiating fin 2-2; By radiating fin 2-2 the heat of conduction is thrown away again, and owing to belong to a kind of closed space in the cabinet, when heat sheds from the top; Cabinet is interior because the relation of negative pressure; Can form a kind of natural wind circulation, thereby reach heat pipe self-cold radiating mode automatically from bottom air inlet mouth inspiration extraneous air.
