Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection range of the present utility model with this.
The GMD low-pressure line-outgoing cabinet that a kind of ventilation and heat is good, comprise cabinet, cabinet door and electric elements, cabinet door is arranged on cabinet, ventilating opening made by the top board of cabinet, the base plate of cabinet makes lower ventilating opening, electric elements are arranged in cabinet, and cabinet is inner latter half of is followed successively by horizontal busbar, vertical bus bar, isolating switch, zero busbar from top to bottom; First half sets gradually instrument control room 1, isolator operation Transmission Room 2 and breaker chamber 3 from top to bottom, owing to being known technology above, therefore no longer repeats.
Innovative point of the present utility model is: breaker chamber lower clapboard 8 makes multiple breaker chamber lower clapboard ventilation hole 9, breaker chamber upper spacer 5 is made multiple breaker chamber upper spacer ventilation hole 10, multiple isolator operation Transmission Room upper spacer ventilation hole 11 made by isolator operation Transmission Room upper spacer 4.
Above-mentioned breaker chamber lower clapboard ventilation hole, breaker chamber upper spacer ventilation hole and isolator operation Transmission Room upper spacer ventilation hole are all set to many rows, often arrange and all have multiple ventilation hole.The ventilation hole of above-mentioned ventilation hole and the original top of cupboard and bottom constitutes an air channel ventilated, as shown by the arrows in Figure 7.
As shown in Figure 6, above-mentioned breaker chamber lower clapboard ventilation hole, breaker chamber upper spacer ventilation hole and isolator operation Transmission Room upper spacer ventilation hole are all bridge type ventilating openings 12.
In order to strengthen ventilation effect, breaker chamber lower clapboard ventilation hole and breaker chamber upper spacer ventilation hole are for shifting to install, breaker chamber lower clapboard ventilation hole is arranged on the side near circuit breaker chamber door 7, breaker chamber upper spacer ventilation hole is arranged on the side away from circuit breaker chamber door, so that improve the radiating effect of electric component 6 in breaker chamber.Isolator operation Transmission Room upper spacer ventilation hole is positioned at above breaker chamber upper spacer ventilation hole, and it is outside to be arranged on instrument control room.
Operation principle of the present utility model is:
As shown in Figure 7, when the circuit breaker adstante febre in breaker chamber, the air of meeting circumference, after ambient air is heated, the ventilation hole naturally moved upwardly through on breaker chamber upper spacer 5 enters isolator operation Transmission Room, then is fallen apart to outside cabinet by the ventilation hole on isolator operation Transmission Room upper spacer 4 and former cabinet top.Meanwhile cold air rises in cabinet bottom cabinet, adds to breaker chamber by the ventilation hole on breaker chamber lower clapboard 8.Material is thus formed the process of an air exchange constantly, the heat sent by circuit breaker is dispersed into outside cabinet continuously, to the last reach heating and the balance of dispelling the heat, thus ensure that the temperature in breaker chamber can not continue raise and exceed Standard, ensure the security of operation of circuit breaker.
