Abstract
The application is provided with a kind of specific method of electrification investigation high-tension apparatus phase shortage.Original application method that the technical program passes through change nuclear phase instrument, during being applied to electrification investigation high-tension apparatus phase shortage, by the display result for reading display instrument, can fast and easily judge a certain phase whether phase shortage, compared to existing technologies, in electrification, can quickly and effectively and easily judge high-tension apparatus whether phase shortage, be suitable for promote the use of.
Description
Technical field
The present disclosure relates generally to power supply technique fields, and in particular to the method and nuclear phase instrument of electrification investigation high-tension apparatus phase shortage
New application.
Background technique
In high-power mechanical-electrical equipment running process, because power supply grid phase load is uneven, certain phase excess load fortune is often had
It carries and causes phase voltage power down suddenly, can not only damage alternating current generator in this way, also electric-control system can be made out of control, equipment is caused to damage
It is bad, and keep goods in process appearance unqualified also due to control is out of control, or even scrap, bring unnecessary economic damage
It loses.
It is detected for the non-full-phase state to high-power mechanical-electrical equipment, the operating method of the prior art are as follows: need first set
It is standby to have a power failure, by D.C. resistance test is mutually carried out, troubleshooting is carried out by resistance, the malfunction elimination time is long, operation
It is cumbersome, it is unfavorable for power supply reliability, it would be highly desirable to improve.
Summary of the invention
In view of drawbacks described above in the prior art or deficiency, it is intended to provide one kind compared to existing technologies, is charging
In the case of, can quickly and effectively and easily judge high-tension apparatus whether phase shortage electrification investigation high-tension apparatus phase shortage method
In a first aspect, a kind of method of electrification investigation high-tension apparatus phase shortage, includes the following steps: two contacts of nuclear phase instrument
Contact is connected with two insulating bars respectively；By two contact contacts respectively with the contact at any phase both ends of high-voltage circuitbreaker；Read nuclear phase
The display result of instrument display instrument: if showing phase difference, judge the phase phase shortage；If display judges the phase without phase difference
Non- phase shortage.
Second aspect, nuclear phase instrument are used to charge the application of investigation high-tension apparatus phase shortage.
In conclusion the application is provided with a kind of specific method of electrification investigation high-tension apparatus phase shortage.The technical program is logical
The original application method for changing nuclear phase instrument is crossed, it is aobvious by reading during being applied to electrification investigation high-tension apparatus phase shortage
Show the display of instrument as a result, can fast and easily judge whether phase shortage is charging feelings compared to existing technologies to a certain phase
Under condition, can quickly and effectively and easily judge high-tension apparatus whether phase shortage, be suitable for promote the use of.
Specific embodiment
The application is described in further detail below with reference to embodiment.It is understood that tool described herein
Body embodiment is used only for explaining related invention, rather than the restriction to the invention.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The application is described in detail below in conjunction with embodiment.
The purpose of actual use of existing nuclear phase instrument is for judging the phase difference between two-phase, and specifically used method is as follows
It is shown:
Assuming that certain line is A phase, one of contact contact X is placed in A phase, another contact contact Y is placed on separately
In one phase, such as 120 ° of display, then it is then negative phase sequence, this mutually should be that explanation, which is positive phase sequence, this mutually should be " B ", such as 240 ° of display
“C”。
In summary, the actual use of nuclear phase instrument is for appraising and deciding the phase sequence between items.
But the method for electrification investigation high-tension apparatus phase shortage provided in the present embodiment, but change the reality of nuclear phase instrument
Border application method, principle are:
Belong to resistance element in view of high-voltage switch gear, it should phase by switching the voltage at a certain phase both ends under normal condition
It is identical, phase difference is not present.
When open-phase fault occurs for high-voltage switch gear, because there are load circuits for tail end of switch, and breakpoint is often switched
Between have electric arc generation, cause failure phase both end voltage phase to be changed, therefore a certain phase both end voltage of test can be passed through
Phase difference, to judge whether this mutually breaks down.
Based on above-mentioned working principle, provide that there are as below methods:
Particularly provideed in the present embodiment it is a kind of electrification investigation high-tension apparatus phase shortage method, include the following steps: by
Two contact contacts of nuclear phase instrument are connected with two insulating bars respectively；By two contact contacts respectively with any phase both ends of high-voltage circuitbreaker
Contact；It reads the display result of nuclear phase instrument display instrument: if showing phase difference, judging the phase phase shortage；If display is without phase
Difference then judges the non-phase shortage of the phase.
By the method for mutually carrying out D.C. resistance test and carrying out troubleshooting by resistance in compared to the prior art
For, method provided in the present embodiment can carry out hot line job, open-phase fault is judged quick and precisely using phasing tester, one
The secondary open-phase fault processing time greatly reduces, and reduces operating procedure, save human and material resources financial resources.
Based on the above embodiment, the specific embodiment provided in the present embodiment can also particularly provide a kind of nuclear phase
Instrument is used to charge the application of investigation high-tension apparatus phase shortage.
Above description is only the preferred embodiment of the application and the explanation to institute's application technology principle.Those skilled in the art
Member is it should be appreciated that invention scope involved in the application, however it is not limited to technology made of the specific combination of above-mentioned technical characteristic
Scheme, while should also cover in the case where not departing from the inventive concept, it is carried out by above-mentioned technical characteristic or its equivalent feature
Any combination and the other technical solutions formed.Such as features described above and (but being not limited to) disclosed herein have it is similar
The technical characteristic of function is replaced mutually and the technical solution that is formed.
