Abstract
The utility model discloses a drawing type high voltage switch cabinet forced wind cooler enforcing the wind cooling to cool the breaker chamber of a switch cabinet. The front plate of the switch cabinet is provided with a wind inlet hole (4), the back part of the wind inlet hole (4) is provided with a blower fan (5) positioned below a middle baffle (3) provided with a wind inlet port (1) at the back part of the switch cabinet, and a valve (2) is provided behind the blower fan (5). The utility model is arranged in a high-voltage draw-out type switch cabinet to enforce the wind cooling to cool the breaker chamber.
Description
Technical field
The utility model relates to the distribution system assembly, particularly the air cooling equipment assembly of pull-out type high-tension switch cabinet.
Background technology
Metal armouring pull-out type high-tension switch cabinet also claims mid-cabinet, is the switchgear assembly of 12kV three-phase alternating current 50Hz single busbar connection and sectionalized single busbar connection system.This equipment is mainly used in being subjected to electricity, sending the electricity and the control of large-scale high-tension motor etc. of power plant, industrial and mineral enterprises and institutions distribution and electric substation of electric industry system, carries out the usefulness of control, protection, supervision.
Development along with electric utility, the increase of power consumption, demand for big electric current, big capacity power consumption equipment is increasing, the cabinet of metal armoring draw out switchgear below main bus bar rated current 2500A can adopt corrosion resistant plate to reduce reasonable disposition such as eddy current by natural heat dissipation system, pressure relief device and the cabinet compartment of cabinet self, realize the control to the temperature rise of cabinet breaker chamber.Along with the increase of circuit breaker rated current, the increase of caloric value, the natural heat dissipation mode of cabinet can't satisfy the heat radiation requirement of cabinet breaker chamber part-structure long-term work.
Summary of the invention
The utility model will solve pull-out type high-tension switch cabinet bad problem that easily causes the accident of breaker chamber heat radiation under big current work situation, a kind of pull-out type high-tension switch cabinet forced air cooling device of the present utility model is provided for this reason, and this device can be implemented wind cooling temperature lowering to the cabinet breaker chamber when described switch cubicle breaker chamber temperature surpasses set point.
For addressing the above problem, its special character of the technical solution adopted in the utility model is to offer fresh air inlet on the header board of described switch cubicle, the fresh air inlet rear is provided with the median septum below that rear portion that blower fan is positioned at described switch cubicle has air inlet, and the blower fan rear is provided with valve.
The utility model should be provided with the support locking shell fragment at the lower edge of described valve and be fixed in the air channel base plate.
Described blower fan is preferably the side blown type blower fan.
Described fresh air inlet can be spaced groove shape fresh air inlet, as the fresh air inlet of 7mm * 70mm.
Described rear portion has the median septum of air inlet, and its air inlet and breaker chamber connect.
Described support locking shell fragment is respectively established one in the valve lower edge near both ends, and is fixed in the air channel base plate just as " " shape, makes valve become to open shape under normal conditions; In case during faults such as breaker chamber is short-circuited, arcing; the high temperature and high pressure gas that produces is most of can discharge cabinet by the ventilation and pressure release device on cabinet top; some can release by the air inlet that median septum and breaker chamber connect; this moment, valve released the closed naturally and locking of the support force that overcomes the support shell fragment under the high pressure effect; the blocking-up high temperature and high pressure gas is discharged before cabinet by the fresh air inlet of described header board, reaches the purpose of protection electric substation's miscellaneous equipment and operator safety.
Machine can make the equal energy of all fresh air inlets air intake of laterally arranging after being positioned at the header board fresh air inlet in the described side blown type.This side blown type blower fan is domestic a production marketing, GFD (S) series of products of producing as Jinhua Wanda's transformer device Co., Ltd.
The blower fan drive motors of this air cooling equipment can be electrically connected with the existing control appliance of temperature and humidity of described switch cubicle breaker chamber.When circuit breaker is positioned at service position work, a live part in the breaker chamber can be along with electric current pass through the generation heat, the breaker chamber temperature increases, the heat of the big more generation of electric current is big more, when the breaker chamber temperature surpasses set point, during as 40 ℃, the relay contact closure of control appliance of temperature and humidity, start blower fan, the blower fan rotation sucks air before the cabinet by the header board fresh air inlet, and the cold air of suction is again by entering breaker chamber with the air inlet of breaker chamber perforation on the valve opened and the median septum, after the breaker chamber heat exchange, hot-air rises and discharges cabinet by cabinet top ventilation and pressure release device, thereby reduces the breaker chamber temperature, reaches the cooling purpose; After 5～8 ℃ of breaker chamber temperature declines, the relay contact of described control appliance of temperature and humidity disconnects, and blower fan quits work, and finishes a cooling circulation.
The utility model is owing to be positioned at below the switch cubicle median septum offering fresh air inlet on the header board of switch cubicle and be provided with blower fan at its rear, the blower fan rear is provided with valve, so when the breaker chamber temperature raise above set point, implementation forced cooling to breaker chamber can to start blower fan under the relay effect of control appliance of temperature and humidity automatically; The valve lower edge is provided with the utility model of support locking shell fragment, then works as breaker chamber and breaks down, and when producing high temperature and high pressure gas, can stop high-temperature high-pressure air flow to release before cabinet, protection equipment and personal security; Blower fan is a side blown type, and air intake is effective.
