Abstract
Disclosed is a method for reducing tripping faults of an air switch. Tripping signal lines and a tripping relay which are connected to the air switch are used. The method includes the following steps of firstly, replacing tripping signal lines which are in poor contact; secondly, setting the tripping relay in an intelligent electric meter to be in a normally-closed wiring state; and thirdly, designing a fault handling instruction card of the air switch. The tripping signal lines are modified, and accordingly tripping faults caused by poor contact of the tripping signal lines are avoided. The manner for wiring the tripping relay is modified, and accordingly response time of the tripping relay is increased, and rate of tripping faults is reduced. Staff can quickly judge reasons of tripping by designing the fault handling instruction card of the air switch and can figure out a solution immediately.
Description
Technical field
The present invention relates to power domain, particularly a kind of method reducing tripping fault.
Background technology
In Utilities Electric Co.'s intelligent grid process of construction, old-fashioned sky is opened and is all replaced by Intelligent air and opens, and it is visual plant in intelligent grid that Intelligent air is opened, and directly in the face of a large amount of client, because this is with extensively, the impact caused is also large.By statistics, in troublshooting, have 36.7% report for repairment be sky open tripping operation cause, be the major failure type of troublshooting, cause puzzlement to client, affect the effect of electrical network good service.
Summary of the invention
Object of the present invention is just to provide and a kind ofly reduces the method that sky opens tripping fault, and it effectively can reduce tripping fault rate in electrical network routine work.
The object of the invention is to be realized by such technical scheme, it includes the empty trip signal line opened of access and tripping relay, includes following steps:
1) the trip signal line of loose contact is changed;
2) tripping relay in intelligent electric meter is set to normally closed wiring state;
3) design sky and open troubleshooting guidance card.
Further, step 1) described in trip signal line include holding wire and to oppose electricity-stealing streamline, streamline one end of opposing electricity-stealing is connected with holding wire one end by binding post, the other end of holding wire is opened with sky and is connected, described binding post is arranged in cartridge, and the other end of streamline of opposing electricity-stealing is provided with Full connected ring plate.
Further, step 2) described in normally closed wiring state be that when line voltage signal is high level, the switching node of relay is closure state, and when line voltage signal is low level, the switching node of relay is off state.
Further, step 3) hollow opening troubleshooting card includes following content:
3-1) cause the reason that circuit breaker can not close a floodgate, and for processing method;
3-2) cause circuit breaker after disconnection ammeter output signal, the reason that circuit breaker does not trip, and for processing method;
Circuit breaker 3-3) is caused to be in operation tripping operation, the reason of circuit breaker normal operation after reclosing, and processing method;
3-4) cause circuit breaker for electronic protection, trip in start-up course, the reason of electric motor starting failure, and processing method.
Owing to have employed technique scheme, the present invention has following advantage:
The present invention, by improving trip signal line, solves the bad and tripping fault problem caused of trip signal linear contact lay; By the improvement to the tripping relay mode of connection, improve the response time of tripping relay, decrease the probability of tripping fault; Open troubleshooting guidance card by designing sky, staff can judge the reason tripped fast, and finds solution in the very first time.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from the practice of the present invention.Target of the present invention and other advantages can be realized by specification below and claims and be obtained.
Accompanying drawing explanation
Accompanying drawing of the present invention is described as follows.
Fig. 1 is theory diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Reduce the method that sky opens tripping fault, include the empty trip signal line opened of access and tripping relay, include following steps:
1) the trip signal line of loose contact is changed;
2) tripping relay in intelligent electric meter is set to normally closed wiring state;
3) design sky and open troubleshooting guidance card.
The present invention, by improving trip signal line, solves the bad and tripping fault problem caused of trip signal linear contact lay; By the improvement to the tripping relay mode of connection, improve the response time of tripping relay, decrease the probability of tripping fault; Open troubleshooting guidance card by designing sky, staff can judge the reason tripped fast, and finds solution in the very first time.
Step 1) described in trip signal line include holding wire and to oppose electricity-stealing streamline, streamline one end of opposing electricity-stealing is connected with holding wire one end by binding post, the other end of holding wire is opened with sky and is connected, described binding post is arranged in cartridge, and the other end of streamline of opposing electricity-stealing is provided with Full connected ring plate.
The Full connected ring plate of streamline of opposing electricity-stealing is enclosed within relay corresponding terminal, adds relay and the contact area of streamline of opposing electricity-stealing, solves the tripping fault problem that traditional trip signal line causes because of loose contact.
Step 2) described in normally closed wiring state be that when line voltage signal is high level, the switching node of relay is closure state, and when line voltage signal is low level, the switching node of relay is off state.
Step 3) hollow opening troubleshooting card includes following content:
3-1) cause the reason that circuit breaker can not close a floodgate, and for processing method;
3-2) cause circuit breaker after disconnection ammeter output signal, the reason that circuit breaker does not trip, and for processing method;
Circuit breaker 3-3) is caused to be in operation tripping operation, the reason of circuit breaker normal operation after reclosing, and processing method;
3-4) cause circuit breaker for electronic protection, trip in start-up course, the reason of electric motor starting failure, and processing method.
The particular content that sky opens troubleshooting card is as follows:
