Abstract

The utility model discloses a high-voltage paralleling reactor and base fixing device. Steel plates are embedded in the positions, which correspond to four corners of a box bottom of a reactor, of the base; the reactor comprises the box bottom and a side wall; and pressing plates which are welded with the steel plates embedded in the base are arranged on the reactor and push against the periphery of the box bottom and the periphery of the side wall of the reactor. The pressing plates and the steel plates embedded in the base are welded together, and the pressing plates simultaneously push against the periphery of the box bottom and the periphery of the side wall of the reactor, so that the pressing plates simultaneously prevent the reactor from moving to two horizontal directions; and after the four pressing plates are fixed at the box bottom of the reactor, the reactor is effectively prevented from moving to the horizontal directions, the reactor and the base are firmly connected together, and the displacement caused by vibration of the reactor is avoided.

Description

The fixture of a kind of high-voltage shunt reactor and base

Technical field:

The utility model belongs to transformer manufacture technology, relates to the fixture of a kind of high-voltage shunt reactor and base.

Background technology:

High-voltage shunt reactor is mainly used in the electrical capacitive charge electric current of compensated line in the high voltage power transmission and transforming system, suppress the rising of light load line end voltage, and suppresses switching overvoltage, thereby reduces the insulation level of system, guarantees the reliability service of circuit.

The vibration of high-voltage shunt reactor can be accompanied by the long-time running of product, and therefore, vibration is the important indicator that affects the reactor product quality.After reactor puts into operation, also can be subject to the impact of the abominable natural conditions such as high wind, heavy rain, sandstorm and earthquake, in order to guarantee the safe and reliable operation of reactor, the reactor body does not allow to produce displacement with respect to base, so the fastness that reactor is connected with base is a key factor of reactor safe operation.

The utility model content:

The utility model proposes the fixture of a kind of high-voltage shunt reactor and base, prevent vibration of reactor and the displacement that causes.

The technical scheme that the utility model adopts is:

The fixture of a kind of high-voltage shunt reactor and base, base position corresponding to four angles at the bottom of reactor box is embedded with steel plate, at the bottom of reactor comprises case and sidewall, be equipped with on described reactor with base in the pressing plate of pre-buried Plate Welding, described pressing plate is against periphery at the bottom of reactor box and the periphery of sidewall.

As preferred embodiment of the present utility model, described pressing plate comprises top board and the lower platen that welds together, described top board and lower platen stagger mutually to guarantee that the inner edge of top board is against the periphery of reactor sidewall, and the inner edge of lower platen is against the periphery at the bottom of reactor box;

As preferred embodiment of the present utility model, described top board becomes the L-type structure with lower platen an ancient unit of weight, respectively with the peripheral structure coupling of peripheral structure at the bottom of reactor box and reactor sidewall;

As preferred embodiment of the present utility model, the thickness of described lower platen equates with thickness at the bottom of reactor box;

As preferred embodiment of the present utility model, the lower surface of described top board is against the upper surface at the bottom of reactor box;

As preferred embodiment of the present utility model, described pressing plate is steel plate structure.

The utility model has the following advantages at least: the utility model with Plate Welding pre-buried in pressing plate and base together, and pressing plate is against periphery at the bottom of reactor box and the periphery of reactor sidewall simultaneously, like this, pressing plate prevents that simultaneously reactor is to the displacement of horizontal both direction, after fixing four block pressur plates at the bottom of reactor box, effectively prevent reactor to the displacement of horizontal direction, also reactor and base are firmly linked together simultaneously, prevented the displacement that causes due to vibration of reactor.

Embodiment:

Below in conjunction with accompanying drawing, embodiment of the present utility model is described:

Present domestic high-voltage shunt reactor generally adopts anchor bolt to be connected with the fixed form of base, concrete mode is: the square hole that at first remains in advance placing anchor bolt on base, after the reactor body is in place, anchor bolt is put accurate location, back-grouting forms integral body with anchor bolt and base again, by anchor bolt, reactor is fixed on base at last.

The shortcoming of this structure is that field procedure is complicated, and the base difficulty of construction is large, and anchor bolt and reactor bottom bracket junction screw thread easy-to-rust, damage during the reactor operation, and then affects the overall performance of reactor product.

The present invention has simplified the connected mode of reactor and base, for the scene provides a kind of simple to operate and safe and reliable fixing means.

The technical solution adopted in the present invention is that the anchor bolt connected mode with reactor and base changes to welding manner.See also Fig. 1 to shown in Figure 7, concrete scheme is:

One, make as Fig. 3, Fig. 4 and shape shown in Figure 7 at four angles at the bottom of reactor box, and namely reactor 3 comprises at the bottom of case 31 and sidewall 33, leaves certain space between the outer rim 311 at the bottom of described case and sidewall 33, in order to accept pressing plate 5;

Two, the pressing plate 5 of four special shapes of processing, this pressing plate 5 is welded by top board 51 and lower platen 53, and top board and lower platen stagger, as shown in Figure 6;

Three, reactor base when construction, the steel plate of the pre-buried suitable size in position corresponding to four angles at the bottom of reactor box, as shown in Figure 5;

Four, the reactor product to on-the-spot in place after, pressing plate 5 is positioned over the position at four angles at the bottom of reactor box, the inner edge 531 that guarantees lower platen is fitted fully with the outer rim 311 on the case base angle, the inner edge 511 that guarantees simultaneously top board is fitted fully with the periphery 331 of reactor sidewall 33, and the lower surface of top board and the upper surface correspondence position at the bottom of fuel tank are fitted fully;

Five, at last with pressing plate and the welding of base pre-embedded steel slab.

The advantage of this fixing means is:

One, " L " type that is shaped as of pressing plate, be welded by two block plates, and this kind processing method is simple to operate, and has saved raw material, avoided being added and the complicated procedures of forming and the waste of raw materials that cause by a monoblock steel plate.

Two, this pressing plate can prevent simultaneously that reactor is to the displacement of horizontal both direction, after fixing four block pressur plates at the bottom of reactor box, can effectively prevent reactor to the displacement of horizontal direction, also reactor and base firmly be linked together simultaneously, prevent the displacement that causes due to vibration of reactor.

Three, simplify the construction of on-the-spot reactor base, only needed pre-buried 4 block plates during the construction of on-the-spot base, after the reactor product is in place, pressing plate and pre-embedded steel slab are welded together has got final product, avoided the scene to carry out the loaded down with trivial details work of second pouring to anchor bolt.

Four, whole fixture structure is simple, and is easy to operate, and satisfies the requirement of reactor product safety operation fully, and after the product installation, overall aesthetics is also better.
