Description
Technical field
The utility model relates to a kind of voltage transformer, refers more particularly to the epoxy pouring type earthed voltage transformer that a kind of anti-overvoltage capacity is strong.
Background technology
In isolated neutral system, due to reasons such as circuit single-line to ground fault, circuit breaking, operation aircraft carrier lines, be often in operation easily excitation voltage instrument transformer generation ferro resonance.When there is ferro resonance, will produce higher than the overvoltage of rated value several times and overcurrent; Magnetically saturated generation also may due to the disturbance of the caused system voltage of the flip-flop, load big ups and downs etc. of overvoltage or system operation mode.Thus cause voltage transformer high pressure winding scaling loss.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of novel voltage mutual inductor, and the housing construction of carbon removing machine is reasonable in design, easy to use, is convenient to mobile.
The utility model is achieved through the following technical solutions: a kind of novel voltage mutual inductor, comprise epoxy resin mixed glue layer, unshakable in one's determination, secondary winding and a winding, described iron core adopts high-quality silicon steel sheet coiling to form, the stem of described iron core is arranged with a winding and secondary winding, the arranged outside of described secondary winding and a winding has epoxy resin mixed glue layer, polyester film condenser paper composite insulating foil is provided with between described secondary winding and a winding, described polyester film condenser paper composite insulating foil is formed by upper and lower two layer capacitor paper and the calendering of middle one deck polyester film coating adhesive.
As preferably, the cross section of described iron core is circular ring-shaped core.
As preferably, a described winding adopts composite coating self-adhesive enameled wire, and the outside of a winding scribbles one deck bonding paint.
The utility model structure is simple, overvoltage ability, main examination be that the magnetic of instrument transformer is close, magnetic is close lower, instrument transformer is more not easy saturated, the probability producing resonance can reduce, and its cross section that the utility model have employed high-quality silicon steel sheet coiling is the ring-shaped core of figure, can increase sectional area unshakable in one's determination like this.Earthed voltage transformer in general system with non effectively earth ed neutral, its voltage factor is 1.9 times, 8 hours, and that is anti-overvoltage capacity is 1.9 times, adopts this kind of iron core the anti-overvoltage capacity of the instrument transformer of same volume can be brought up to 2.5 times;
Instrument transformer winding can be adhesion-molded voluntarily at short notice with drying the method for accompanying, be arranged in uniformly on layer insulation PMP, the gap of turn-to-turn can also be filled up by the bonding paint after simultaneously dissolving, thus improves the local discharging level of instrument transformer, also enhances the mechanical strength of product.Layer insulation, adopt (PMP) polyester film condenser paper composite insulating foil, it is a kind of insulating material by upper and lower two layer capacitor paper and the calendering of middle one deck polyester film coating adhesive, has good dielectric property and higher mechanical strength.
