With the continuous production and the increasingly raising of living standards of the people of modern industry, power consumer is to the quality of power supply and confession Electric reliability requirement more and more higher.As the terminal power distribution complete sets of products that region be directly facing user, box-type substation is with its complete property By force, invest instant effect, small volume, take up an area few, load center can be goed deep into, the end quality of power supply is improved, it is easy to install, easily with The advantages of surrounding environment is mutually coordinated, which obtains, quickly develops and is widely applied.Using the Intelligent box type of Distribution Automation Technology Transformer station can ensure power supply continuity, improve power supply reliability and the quality of power supply, realize unattended and remote monitoring with Management.
The intellectuality of box-type substation is exactly by computer technology, microelectric technique, Power Electronic Technique, network technology etc. Applied to the device for switching such as breaker and controller switching equipment, the intellectuality of system is realized, is allowed to possess control, measurement, working condition The functions such as teletransmission, the setting of a Protection parameters distant place, accident classification judgement, protection and record, and combine network technology, be wirelessly transferred skill Art etc. realizes distant place Centralized Monitoring and hierarchical management, substitution it is artificial it is on duty, make an inventory instrument, failure judges immediately, cut off and The manual workings such as record, strengthen power supply reliability, the security of box-type substation, improve the quality of power supply.
Low pressure is using the three-phase voltage and three-phase current on platform area intelligent testing terminal-pair distribution transformer low-pressure side circuit Carry out AC sampling.Because, without space, high pressure is direct by intelligent monitoring unit using distribution DTU in the narrow and small cabinet of installing space It is installed in ring main unit secondary chamber.Present invention employs environmentally friendly gas as insulating materials, SF6 compensate for gas isolated not Foot.
For response environmental protection and health requirement, ring main unit is designed to environmentally friendly gas isolated switchgear.Height is pressed off Equipment is closed to be designed to go out the inlet-outlet line that mode facilitates cable on enterprising.
Because, without space, ring main unit is using one or two Combined design theories, and ring main unit is each single in the narrow and small cabinet of installing space Independent distribution power automation terminal-distribution the DTU of member installing, enables each unit to be independently controlled, and realizes to a distant place one " remote signalling, remote measurement and the remote control " of secondary device.
In order to realize the intelligentized control method of box-type substation, low pressure is set to use the temperature of intelligent testing terminal-pair transformer Monitoring, low-pressure line-outgoing status monitoring and full electric quantity acquisition;Transformer load rate can be monitored simultaneously, the orderly of electric automobile is realized Charge Management.Power supply reliability is improved, improves the quality of power supply, managerial skills are lifted, Intellectualized monitoring management can shorten thing Therefore processing time, power failure range is reduced, the expense of operation maintenance is reduced.
The present invention is using cable broadband internet communication mode, the GPRS wireless communication modes or electricity of band signal amplification module Power carries news mode etc..
10kV ring main units using breaker unit as transformer inlet wire, can not only the normal load current of break-make, and Can the certain short circuit current flow of break-make.Can also the automatic trip under protective relaying device effect, excision short trouble.
In order to realize the intelligentized control method of box-type substation, set low pressure using intelligent testing terminal (TTU) to transformer Temperature monitoring, low-pressure line-outgoing status monitoring and full electric quantity acquisition;Transformer load rate can be monitored simultaneously, electric automobile is realized Orderly Charge Management.
As can be seen from the above description, the above embodiments of the present invention realize following technique effect:
The box-type substation of the present invention passes through intelligence by being provided with intelligent monitoring unit 22 on low-voltage distribution equipment 20 Monitoring unit 22 can realize the collection of the three-phase voltage and three-phase current on the conductive track to low-voltage distribution equipment 20.In tool During body use, by the way that intelligent monitoring unit 22 is arranged in the low-voltage distribution cabinet 21 of low-voltage distribution equipment 20, wherein, it is low The conductive track of press-fitting electric installation 20 is connected with intelligent monitoring unit 22, thus by the electric current in intelligent monitoring unit 22 and Voltage acquisition module realizes the collection to current information and information of voltage, is then believed the voltage collected by communication module Breath and current information are sent to control terminal 40, so as to realize the remote monitoring of operating personnel.
Compared to the scene that existing box-type substation depends on operating personnel for the collection of information of voltage and current information Collection, box-type substation of the invention can realize the management of a unattended and distant place, improve power supply reliability and the quality of power supply, The high request that user is supplied electric energy is met, is asked so that the reliability for solving box-type substation of the prior art is poor Topic.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
