Description
Technical field
The present invention relates to a kind of power equipment wiring testing device, particularly a kind of high-voltage electric energy measurement machine utilization emulation
Device.
Background technology
Substation is generally by switching, the composition such as high-voltage meter, transformer and low-voltage cabinet, is set when substation checks and accepts metering
When standby, general electric current, voltage transformer and electric energy meter fit together after individually examining and determine, due to kilowatt-hour meter and transformer interface
Line is at least 7-12, wiring error often occur phase fault or it is alternate over the ground etc., plus wiring caused by secondary lead wires
Up to 28 kinds of mistake, in addition since measuring room personnel are unstable or operated by casual labour, more and more kilowatt-hour meters and mutual inductor
The frequent wrong of connection, such as pressure-wire phase sequence mistake, voltage and current line dislocation, PT multiple groundings, in some units 1 year
Occurs misconnection problem for several times, the batch meter of a 10kV or 35kV is ten hundreds of due to being lost caused by wiring error, due to connecing
Phenomena such as line mistake causes PT explosions, damages is also commonplace, and each side then mutually shifts responsibility onto others for the ownership of responsibility, often responsibility
Construction team or equipment production firm are pushed to, the safety of stability and personnel to electric system also results in great threat.Study carefully it
Reason, is because when new user accesses, does not have load in high-tension line, also without corresponding phase voltage and phase current, moreover, mesh
Preceding many metrology and measurement equipment are all high with low school, it is impossible to reflect actual conditions.
The content of the invention
For overcome the deficiencies in the prior art, the present invention, which provides one kind, can realize that height emulates, and protect equipment and personnel
The measuring equipment load simulator of safety.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of measuring equipment load simulator, including imitated by what current simulations branch and voltage dummy branch parallel connection were formed
True circuit, the 380V exchange inputs of a termination three-phase four-wire system in the emulation circuit, other end reception check equipment.
The current simulations branch includes sequentially connected pressure regulator T1 and high pressure current lifting device T2, the pressure regulator T1 settings
There is GSS Gear Select Switch.
The voltage dummy branch includes sequentially connected circuit breaker Q F, drop/pressure regulator T3 and booster T4.
The emulation circuit is connected with A.C. contactor CJ between input is exchanged with the 380V.
The equipment to be checked includes measuring equipment, electric energy meter and electric energy meter quantitative analysis instrument.
The beneficial effects of the invention are as follows：The current simulations branch and voltage dummy branch of the present invention is capable of providing to be checked set
Standby high-tension current, phase voltage and phase current in actual work, before formal be powered, is carried out using the simulation load of network voltage
Energization is simulated outside electric power system, since the simulator possesses defencive function, even if the wiring error of equipment to be checked will not
Damage of product or explosion are caused, work efficiency can be effectively improved, preferably protect equipment and the safety of personnel, is reduced because wiring is wrong
The problem of causing explosion to cause employee to be laid off by mistake.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is one of embodiments of the present invention schematic diagram；
Fig. 2 is two schematic diagrams of embodiments of the present invention.
Embodiment
Reference Fig. 1, Fig. 2, a kind of measuring equipment load simulator, including by current simulations branch and voltage dummy branch
The emulation circuit that parallel connection is formed, the 380V exchange inputs of a termination three-phase four-wire system in the emulation circuit, other end reception inspection
Look into equipment such as measuring equipment, electric energy meter and electric energy meter quantitative analysis instrument etc..The current simulations branch includes sequentially connected tune
Depressor T1 and high pressure current lifting device T2, the pressure regulator T1 are provided with GSS Gear Select Switch such as 10KV, 20KV, 35KV.The voltage
Dummy branch includes sequentially connected circuit breaker Q F, drop/pressure regulator T3 and booster T4.Handed over the 380V in the emulation circuit
A.C. contactor CJ is connected between stream input.
In the present embodiment, booster T4 output voltages such as 10kV, 20kV, 35kV, high pressure current lifting device T2 output current are such as
10th, 50,75,100A, phase voltage, phase current are exactly corresponding emulation capacity such as 10kV × 1.73 × 100A=1732kVA.This hair
Bright simulator emulation capacity be O.1-60000kVA, voltage 10kV, 10/ √ 3kV (expressions of √ 3 radical sign 3), 20kV,
20/ √ 3kV, 35kV, 35/ √ 3kV etc., monophase current before formal be powered, utilize the simulation of network voltage in below 1000A
Load is powered outside system and simulates energization, since the simulator possesses defencive function, even if the wiring of equipment to be checked is wrong
Mistake will not cause damage of product or explosion, can effectively improve work efficiency, preferably protect equipment and the safety of personnel, reduce
Because explosion causes employee to be laid off caused by wiring error the problem of.
