Abstract
The utility model relates to a kind of high voltage customer high and low pressure metering system simultaneously, comprise transformer, high-pressure side ammeter and low-pressure side ammeter, the high-pressure side of transformer be connected high-pressure side ammeter between mains side, transformer low-pressure side be connected low-pressure side ammeter between load side.Native system, when high-pressure side taximeter meter breaks down, by the electricity contrast of high and low pressure side two pieces table meter, can find the wiring error of electric energy meter comparatively rapidly.
Description
Technical field
The utility model belongs to Regulation field, relates to the metering of power consumption, and especially a kind of high voltage customer high and low pressure is metering system simultaneously.
Background technology
In recent years, along with carrying out of Guo Wang company " full collection, all standing, control in full " developing goal comprehensively, high-voltage intelligent ammeter is just at spread.Intelligent electric meter can realize remote collection, monitoring, data storing function, greatly advances reform and the innovation of power marketing work.But change table meter on a large scale, while guaranteeing the new clothes time limit, be difficult to the wiring accuracy rate of guarantee 100%.And, in use once table meter breaks down, if non-Timeliness coverage causes extreme influence by the economic benefit of company, simultaneously single metering method is also given and is lost remedying of electricity and cause certain difficulty, and therefore single metering method cannot meet our metering requirements.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of high voltage customer high and low pressure metering system simultaneously, this system obviates the loss because connection box of electric energy meter mistake causes electric system economy.
The technical scheme that the utility model technical solution problem adopts is:
A kind of high voltage customer high and low pressure metering system simultaneously, comprise transformer, high-pressure side ammeter and low-pressure side ammeter, the high-pressure side of transformer be connected high-pressure side ammeter between mains side, transformer low-pressure side be connected low-pressure side ammeter between load side.
And described high-pressure side ammeter is connected with the high-pressure side of transformer by combined connection box, and combined connection box is also connected with voltage drop recorder and load governor.
And described low-pressure side ammeter is connected with the low-pressure side of transformer by combined connection box, and combined connection box is also connected with voltage drop recorder and load governor.
And, in the high-pressure side of transformer and be all connected with current transformer between low-pressure side and the combined connection box of its homonymy.
And described high-pressure side ammeter is phase three-wire three ammeter.
And described low-pressure side ammeter is three-phase and four-line ammeter.
Advantage of the present utility model and good effect are:
1, native system is when high-pressure side taximeter meter breaks down, and by the electricity contrast of high and low pressure side two pieces table meter, can find the wiring error of electric energy meter comparatively rapidly.
2, under the mode of connection that native system measures at this kind of high-low pressure simultaneously, when high-pressure side taximeter meter breaks down, the foundation that the energy data of low pressure side meter can be collected as demand charge, has ensured the economic benefit of electric company further.
Accompanying drawing explanation
Fig. 1 is the connection diagram of native system.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of high voltage customer high and low pressure metering system simultaneously, comprise transformer, high-pressure side ammeter, low-pressure side ammeter, voltage drop recorder and load governor, respectively be connected high-pressure side ammeter, voltage drop recorder and load governor with between mains side by combined connection box in the high-pressure side of transformer, be respectively connected low-pressure side ammeter, voltage drop recorder and load governor with between load side by combined connection box in the low-pressure side of transformer.Described high-pressure side ammeter is phase three-wire three multifunction electric meter, and described low-pressure side ammeter is three-phase and four-line multifunction electric meter.And, in the high-pressure side of transformer and be all connected with current transformer between low-pressure side and the combined connection box of its homonymy.
The effect here of described voltage drop recorder is: the time of record high-tension electricity user PT decompression and number of times.It utilizes a phase-shift circuit to monitor PT secondary circuit; utilize CT secondary current as working power; sample by the break-make of this power supply of Control from PT secondary circuit; when measuring normal or whole grid power blackout; decompression instrument not record, when a phase, two-phase or three-phase pressure loss and measuring apparatus break down, voltage drop recorder is started working; the time of recording pressure loss and number of times provide reliable digit foundation for mending quantity calculation, and send alerting signal simultaneously.
The effect here of described load governor is: the intelligent controller being master element with intelligent CPU, Main Function is receive the overload signal born control management terminal and send, and carry out the controller of certain time-delay, there is warning, the function of delay tripping and instruction overload time.
Described high-pressure side ammeter is identical with the function of low-pressure side ammeter, all be used to metering and gather user side energy information, but the energy information unlike low-pressure side ammeter record is mainly used to contrast, not as the foundation that demand charge is collected with the energy information of high-pressure side ammeter record.The mode of connection that this high-low pressure measures simultaneously, comply with the job requirement of high-voltage intelligent ammeter spread, realize following functions: 1. when high-pressure side ammeter breaks down, by the electricity contrast of high and low pressure side two pieces table meter, the wiring error of electric energy meter can be found comparatively rapidly.2., under the mode of connection that this kind of high-low pressure measures simultaneously, when high-pressure side taximeter meter breaks down, the foundation that the energy data of low pressure side meter can be collected as demand charge, has ensured the economic benefit of electric company further.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from utility model design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
