Description
Technical field:
This product is a kind of measuring apparatus of electric energy, and particularly a kind of 10KV substation transformer hangs down comprehensive metering device case, is a kind of batch meter of energy accurate measurement distribution transformer power load.
Background technology:
At present, the substation transformer of 10kV 500kVA and following capacity, the batch meter that uses is a minute body structure, has the very big problem of power load error in dipping, can not satisfy " electric power meter technical management rules " DL448-2000 requirement.As everyone knows: the difference of electric energy user load, cause transformer three-phase load imbalance, can cause that electric energy meter produces big error in dipping, it is unclear to cause power supply enterprise and electric energy user distribution line loss to divide, by inferior frequent initiation electricity charge dispute.
Summary of the invention:
For strengthening power supply enterprise's line loss management, solve the problem that exists at present, the utility model provides a kind of 10KV substation transformer low-voltage comprehensive measuring apparatus case, it adopts monolithic construction comprehensive metering case, can reduce the electric quantity consumption between the measuring instrument, make the whole measuring error of measuring instrument satisfy " electric power meter technical management rules " DL448-2000 requirement.Use novel low-voltage comprehensive batch meter to import power consumption into the electricity consumption mis system, just check electric weight, improved and copied the qualification rate that nuclear is received with the meter reading personnel by electric energy meter 485 interfaces and negative control device, realize the information-based and electric weight of measuring control examine purpose.Use this product can make things convenient for the measurement verification personnel to carry out the electric energy meter field verification and equipment is rotated on schedule, also can adjust the size of load flexibly, solved and changed transformer in the past and will change measuring apparatus, reduced the cost of electricity consumption enterprise.Improved the reliability of metering outfit safe operation.
The utility model is achieved through the following technical solutions:
A kind of 10KV substation transformer low-voltage comprehensive measuring apparatus case is made of casing and insulating barrier, it is characterized in that: casing is established forward and backward door, establishes hinge in the forward and backward door, and adds anti-theft puzzle lock, sealing lead; Insulating barrier front dress electric energy meter, negative control device, the three-phase and four-line terminal box, behind the insulating barrier and dress current transformer, copper bar, once load output, input cable connection.
Casing adopts the enclosed construction of stainless steel material, and base, batch meter dividing plate place and annex material adopt the galvanized angle iron material to make.
Casing is provided with the instrumental observation mouth, and the instrumental observation mouth is made of colourless, transparent material.
Useful technique effect of the present utility model is: it adopts monolithic construction comprehensive metering case, can reduce the electric quantity consumption between the measuring instrument, makes the whole measuring error of measuring instrument satisfy " electric power meter technical management rules " DL448-2000 requirement.Use novel low-voltage comprehensive batch meter to import power consumption into the electricity consumption mis system, just check electric weight, improved and copied the qualification rate that nuclear is received with the meter reading personnel by electric energy meter 485 interfaces and negative control device, realize the information-based and electric weight of measuring control examine purpose.
