Description
Technical field
The utility model belongs to the AC voltage regulator technical field of contact type structure, specifically relates to a kind of pressure stabilizer with smog sampling protection.
Background technology
Contact AC voltage regulator in the market, the closed-loop control system being formed by the pressure regulator of particular design or transformer and controller (or control circuit), by automatic adjustment to reach the electric device of regulated output voltage object, referring to Fig. 1, conventionally by contact autotransformer, automatic control circuit and servomotor, formed.This class voltage stabilizer, adopt stepless voltage regulation, the output accuracy of product is high, waveform distortion is little, antijamming capability is strong, cost performance is high, and market coverage scope is wide, but finds according to production and sales for many years, the failure rate of this type of voltage stabilizer is also higher, main cause is as follows: 1,, due to motor wearing and tearing or control circuit board fault, cause that pressure regulating device is malfunctioning, as motor wiring board damages, cause motor reversal to coil lower position, form the low-resistance situation of high voltage, input voltage raises, and transformer magnetizing current increases, and very easily makes that voltage stabilizer coil is overheated to be burnt, 2, because this type of voltage stabilizer is autotransformer structure, when input voltage is low, the capacity loss of transformer output, the correlation standard of voltage stabilizer, when this type of voltage stabilizer is inputted in low-voltage, user should fall to hold and use, if input voltage range is the voltage stabilizer of 160V～250V output 220V, when input voltage is during lower than 198V, should start to fall to hold and use, when input voltage can only be used 50% of nominal load during at 160V, what this was voltage stabilizer falls appearance characteristic, but in actual use, polytrope due to line voltage, terminal user is difficult to accomplish fall in time hold and uses, conventionally the load of using when voltage is high, when input voltage is low, voltage stabilizer uses in overload, therefore voltage stabilizer very easily transships use, make that coil is overheated to be burnt out, 3, due to product, adopted carbon brush and carry out pressure regulation, there are wearing and tearing in carbon brush in movement, and after long term wear, carbon brush there will be sparking, and as do not processed in time, the coil of carbon brush contact position can generate heat and burn out.Due to above reason, after voltage stabilizer coil heating, the turn-to-turn insulation of coil can be destroyed, and after long-time energising, voltage stabilizer very easily burns out, can initiation fire when serious etc. serious accident.Although existing overheating protection, overcurrent protection and overvoltage protection in regulator products design, but because the pressure regulation of this type of voltage stabilizer is moved and realized on autotransformer coil by carbon brush, not fixing of changeable and user load due to electrical network in real work waited many factors, voltage stabilizer carbon brush position is changeable, the heating position of coil also changes at any time, due to not fixing of trouble spot, actual overheating protection cannot accurately be sampled, and can not avoid coil to burn out completely; The working current of overcurrent protection sampling voltage stabilizer is protected, because this type of voltage stabilizer has input voltage, need fall when low and hold the characteristic of using, so same working current current value when voltage is high is normal signal, and when voltage is low, time this electric current be exactly likely abnormal signal, so overcurrent protection also cannot be protected accurately and reliably; Though the overvoltage protection of product can be protected the safety of output load; if but rising or the inner pressure regulating device of voltage stabilizer due to line voltage is abnormal after overvoltage; can make the autotransformer of voltage stabilizer inside enter magnetic saturation state; coil can damage; voltage stabilizer itself can damage; therefore the overvoltage protection of voltage stabilizer can only be protected the load of voltage stabilizer rear end, can not protect voltage stabilizer self.
Therefore above-mentioned existing safeguard measure all has limitation separately in the process of implementation; burning of coil is difficult to accomplish to protect timely and effectively; the mode that on market, most of voltage stabilizers are normally exported by cut-out voltage stabilizer for the protection of above-mentioned measure in addition realizes; and in actual use because voltage stabilizer inside still has voltage; when coil fault, accident still has and may further spread, and cannot thoroughly effectively avoid security incident.
