(1) if the capacitor tower adopts the pattern of series connection, the low terminal voltage of high-pressure tower can be very high, like this in order to satisfy electric requirement, high-pressure tower bottom insulation will be very high, and simultaneously in order to satisfy the mechanical performance requirement, insulator is higher, average diameter will be thicker, and difficulty of processing is just larger;
(2) because whole capacitor tower voltage is very high, high tower and low tower voltage difference are just very large like this, for the spacing that satisfies electrical safety high tower and low tower is just very large, will certainly cause the increase of whole capacitor tower floor space;
(3) along with the increase of compensation capacity, every layer capacitor unit and number will increase in the capacitor tower, have in addition reach 6 also, so just require the anti-quick-fried ability of capacitor unit to strengthen.
The utility model content
In order to address the above problem, the utility model provides a kind of novel capacitor tower for ac filter or shunt compensation, it is composed in parallel by one first trourelle and one second trourelle, and described the first trourelle is connected to form by a plurality of tower layers, and described the first trourelle is identical with the second little tower structure; The top of described the first trourelle is connected with the bottom and is connected with the bottom with the top of described the second trourelle that metal tube is female to be connected, described the first trourelle inter-chamber tower layer be connected the inter-chamber tower layer of trourelle and be connected with a current transformer by soft whipping wire respectively.
Preferably, described each tower layer connects by insulator, and described each tower layer comprises a capacitor group and a bracing frame, and support frame as described above is positioned at capacitor group below.
Preferably, the end of the capacitor group of its each adjacent towers layer connects by soft whipping wire.
Preferably, described capacitor group comprises two row's capacitor units, and described two row's capacitor units are symmetrical arranged.
Preferably, described each row's capacitor unit links together.
Preferably, the sleeve pipe of described capacitor unit outwardly.
Preferably, grading ring optionally is housed around the support frame as described above.
The utlity model has following beneficial effect:
The insulator of (1) two trourelle bottom is equivalent to the low-pressure end of high-pressure section, and its insulating requirements is not high, so the easy type selecting of insulator;
(2) two trourelles adopt modes in parallel to connect, and the two structure is identical, and the same layer potential difference in two towers is very little, and the gap variable between therefore is little, thereby saves floor space;
(3) by shunt capacitor being placed on respectively in two trourelles, Parallel-connected Capacitor quantity is equivalent to reduce half in every layer of trourelle like this, and corresponding anti-quick-fried energy has also just reduced.
