Description
Technical field
This utility model relates to the technical field of a kind of power equipment, particularly relates to a kind of combined type gas-liquid-solid sealed pole.
Background technology
The vacuum circuit breaker of existing popularization and application have employed pole structure more, mostly is arc-chutes and live part uses epoxy resin integration sealing, major advantage volume is little, simple in construction, insulation and weather resistance relatively good.
Vacuum circuit breaker is as being used in power system protecting and control electrical equipment using; there is in power system very important effect; traditional vacuum circuit breaker is all the parameter being gathered and being measured voltage, electric current by comprehensive relay protection device, is controlled vacuum circuit breaker；All it is arranged in switch cubicle as independent unit for gathering current parameters amount and the current transformer of voltage parameter amount, voltage transformer, the electromagnetic type structure that current transformer, voltage transformer the most generally use.Its volume is big, quality weight, and installation workload is big, and cost is high.Information conversion and transmission link between chopper, comprehensive relay protection device, current transformer and voltage transformer are the most more complicated, and the ageing of entirety is affected.
Along with intelligent power network construction is carried out by country, intelligent breaker will become important ingredient, and as intelligent breaker, premise is to have the parameter amount to electrical network is relevant to be acquired, and even requires have integrated protection, control function.It is therefore desirable to design a kind of in-built electrical minor voltage transformer and the integrated solid sealed pole of electronic type voltage transformer.
Summary of the invention
The utility model discloses a kind of combined type gas-liquid-solid sealed pole, electronic current mutual inductor, voltage transformer are cast for one with pole by this device, make full use of pole insulating space, arranging electronic formula current-voltage transformer, does not increase handcart circuit breaker installing space and can reduce the faults such as ferromagnetic resonance, overvoltage, the external short circuit of secondary and cause voltage transformer explosion accident.
For reaching above-mentioned purpose, technical scheme disclosed in this utility model is a kind of combined type gas-liquid-solid sealed pole, and it includes that electronic type voltage transformer, electronic current mutual inductor, secondary leading-out terminal, vacuum interrupter and static contact connect terminal；The top of vacuum interrupter connects voltage-type current transformer, and the bottom of vacuum interrupter connects voltage-type voltage transformer, voltage-type current transformer arranges static contact and connects terminal, voltage-type voltage transformer arranges secondary leading-out terminal.
Electronic type voltage transformer, electronic current mutual inductor, secondary leading-out terminal, vacuum interrupter and static contact connect terminal and are cast for an entirety, epoxy resin layer is wrapped up outside entirety, described electronic type voltage transformer bottom arranges groove, and secondary leading-out terminal is arranged on inside grooves.
The beneficial effects of the utility model are: which raises the integrated level of product, reduce the transmission of each link information and make mistakes, improve the ageing of information transmission, can be removed the transformer room etc. of switch cubicle, can effectively reduce the volume of switch cubicle.Due to transformer and pole one, during maintenance, handcart pull-out can greatly be facilitated maintenance.Owing to voltage transformer uses electronic type product, the faults such as ferromagnetic resonance, overvoltage, the external short circuit of secondary can be reduced and cause voltage transformer explosion accident.Simultaneously because the heat-stable current of current transformer consistent with chopper (traditional small area analysis is more much lower than chopper than transformer heat-stable current), can effectively prevent the current transformer explosion caused because of system short-circuit.Systematic current measurement, current protection, voltage measurement, the effect of voltage protection is also had in addition to all functions possessing traditional pole.
