The purpose of this utility model is to provide small generation set composite type installing type generator cell equipment in one, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
Small generation set composite type installing type generator cell equipment in one, comprise high pressure P T room and excitation change room, high pressure P T room and excitation become room combination and install constitution equipment casing, welding three high-tension switch cabinets are arranged in order along equipment box Width, the model KYN28-12 type of high-tension switch cabinet in described high pressure P T room; Excitation becomes indoor and arranges excitation transformer.
As further program of the utility model: the height of described high-tension switch cabinet and the free height of equipment box are consistent, the bus-bar room sidewall of high-tension switch cabinet leaves access hole for convenience detach.
As further program of the utility model: the installation panel of described high-tension switch cabinet is installed generator outlet measuring instrument, the position of the corresponding measuring instrument in equipment box side arranges observation window, and observation window is transparent organic glass window.
As further program of the utility model: the inner high voltage bus of described equipment box adopts insulating barrier and silicon rubber insulating sleeve turnover.
As further program of the utility model: described equipment box is sealed by special steel plate or aluminium alloy plate and is made.
As further program of the utility model: the inside of described equipment box arranges forced ventilation structure, namely high pressure P T indoor location has two one, the air-conditioning processed of 3P, and excitation change is equipped with ventilating fan two in room, and ventilating fan connects attemperating unit.
As further program of the utility model: the pre-buried 10# channel-section steel of base foundation loading end of described equipment box, the end face of 10# channel-section steel is a little more than basic loading end, and the ground lead bottom equipment box should be no less than two, and ground lead connects earth resistance.
Compared with prior art, the beneficial effects of the utility model are: concentrated by all dispersing apparatus in loading movable whole-sealed, anti-condensation equipment box, compound mode is versatile and flexible, single devices technology maturation.This equipment box is installed in factory, delivers to engineering site after debugging.Work on the spot only need carry out the connection of the corresponding basis of equipment box and line, can complete generator outlet fitter's work very soon, not only effectively accelerate installation progress, simultaneously because it is installed for combining, effectively saving and taking up an area space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the outlet structure schematic diagram of high pressure P T indoor.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, small generation set composite type installing type generator cell equipment in one, comprise high pressure P T room 2 and excitation change room 3, high pressure P T room 2 and excitation become room 3 and combine installation constitution equipment casing, welding three high-tension switch cabinets 1 (also can be other fixed high-pressure cabinet) are arranged in order along equipment box Width, the model KYN28-12 type of high-tension switch cabinet 1 in described high pressure P T room 2.
Excitation change arranges excitation transformer 4 in room 3, and be convenient transportation, the Width of excitation transformer 4 does not generally allow to widen, if according to actual needs, when cabinet requires to increase not, can by equipment box extended length, and excitation becomes room 3 can transverse arrangement of turbo.
The described height of high-tension switch cabinet 1 and the free height of equipment box are consistent, and the bus-bar room sidewall of high-tension switch cabinet 1 leaves access hole for convenience detach.
The installation panel 6 of described high-tension switch cabinet 1 installs generator outlet measuring instrument, comprise the measuring instruments such as generator outlet voltage, electric current, power, frequency, power factor, electric energy, and all measuring instruments require to have teletransmission communication interface and 4 ~ 20mA weak electric signal interface.Measuring instrument on high-voltage board front panel should be able to be visible outward at equipment box, therefore require that the corresponding meter location in this side of equipment box arranges observation window, and observation window adopts transparent organic glass window or other transparent material.
The inner high voltage bus of described equipment box adopts insulating barrier+silicon rubber insulating sleeve turnover, and concrete outlet position should cooperatively interact with generator outlet copper bar position and determine.
The structure of described equipment box should have functions of waterproof and dustproof, adopts special steel plate or aluminium alloy plate to make, through preservative treatment, and long service life, simultaneously good looking appearance.
The inside of described equipment box arranges forced ventilation structure, is namely provided with two one, the air-conditioning processed of 3P in high pressure P T room 2, and excitation change is equipped with ventilating fan two in room 3, and make ventilating and cooling good, ventilating fan has attemperating unit, automatically starts and close by design temperature.
The base foundation loading end of described equipment box answers pre-buried 10# channel-section steel, and the end face of 10# channel-section steel is a little more than basic loading end (≯ 3mm), and the ground lead bottom equipment box should be no less than two, and guarantees earth resistance.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
