Description

A kind of wire box for mesohigh generator

Technical field

A kind of corollary equipment of internal combustion engine driving generating set no-brush synchronous generator is the utility model is related to, is specifically related to A kind of and wire box for mesohigh generator.

Background technology

The wire box of low voltage generator is integral, and mostly thin in profile for cost and integrally-built consideration Wall pieces.Because the power of former low voltage generator is not too large, so the vibration of generator entirety is smaller, wire box and hair Without the effect of consideration damping when motor body connects.Nearly 2 years low voltage generators are just considered to subtract because power incrementally increases Shake.

Wire box in the past is integrated sheet-metal chest on casing 15, is divided into top box and nowel by central dividing plate (see Fig. 1). Control element and three-phase copper bar 14 are placed typically in top box, plays a part of support component.Exciter and zero is placed in nowel Phase copper bar 16, play protection exciter and logical wind action.In top box, pressure regulator 12 and electric capacity 11 are bolted on the right side On side plate 13, three-phase copper bar 14 is fixed on the central dividing plate of wire box.Three-phase copper bar 14 and pressure regulator 12 and electric capacity 11 are upper In the same space of case, without high and low voltage isolation.

But in mesohigh generator, because the output voltage of generator is higher, in generator operation, if passed through When pressure regulator is to adjust the voltage of generator, it is necessary to ensure personal safety, then require that control section must high and low voltage isolation.

In addition, zero phase copper bar 16 is fixed on by insulated terminal in the nowel of wire box 15, if client needs to install mutually The control elements such as sensor, then there is no fixed position in nowel, equally, without the position for fixing control element in top box yet.

To sum up, no matter existing wire box is from spatially to the requirement that mesohigh generator is unsatisfactory in electrical design.
