Description
Technical field
The utility model relates to electric power apparatus renovation technique field, particularly relates to a kind of secondary earth leakage protective coupling box.
Background technology
Present Guo Wang company is wideling popularize intelligent meter transformation project; concentrated gas meter box is replaced to use with single table case; so single table case group will lose intermediate earth leakage protective, and the table line that connects simultaneously entering table is connected the joint that can form two or more exposure with the service conductor got off from rod up-leading.Pertinent regulations are protected in three grades of leakages of must installing that the metering device of such assembling and connection type had not both unsightly met state's network planning fixed yet, and there is potential safety hazard, easily endanger personal safety.Another problem is that maintenance personal does not have obvious cut-off point when overhauling metering device, and need the empty circuit breaker in drawing first class of protection (namely low-voltage comprehensive distribution cabinet is commonly called as JP cabinet), cause more user to have a power failure like this, meaningless expands power failure area.
Traditional mode of connection:
Traditional wired mode 1: service conductor enters table case from first piece of table, wire is linked into through after 1 to 5 piece of table the control switch that the 6th piece is shown inlet wire below table case.The control switch of inlet wire shown respectively by first piece of table in table case from main power line top connection access to the 5th piece of table inlet wire.More difficult by landform restriction wiring at table case nipple.A problem be if user move table and replacing table time, because of power line from table case in pass, must table case destroy could change.So just form unnecessary goods and materials waste.
Traditional wired mode 2: service conductor is from after house lead in shelf is fixing, on the phase line that every block table is connected on service conductor from the control switch wire of drawing 1 2*10 of table inlet wire respectively and the neutral line, show case inlet wire and the phase line of service conductor and the joint area of the neutral line to be exposed to for a long time in external environment, insulating tape is aging to come off, and causes personal electric shock casualty accident may to Maintenance and Repair personnel.
Traditional wired mode 3: the parallel lines that after service conductor is fixing from house lead in shelf, the control switch of access first piece table inlet wire then draws a 2*10 from the control switch of table inlet wire again access the table inlet wire control switch of second piece of table, then the rest may be inferred to access the table inlet wire control switch of the 3rd piece of table from the parallel lines that the table inlet wire control switch of second piece of table is in an extraction 2*10.Be linked on the table inlet wire control switch of the 4th piece of table if table case is many drawing the parallel lines of a 2*10 from service conductor, then the rest may be inferred to access the control switch of the table inlet wire of the 5th piece of table from the parallel lines that the table inlet wire control switch of the 4th piece of table is in an extraction 2*10.The parallel lines being in an extraction 2*10 from the table inlet wire control switch of the 5th piece of table again access the control switch of the table inlet wire of the 6th piece of table, and the rest may be inferred.Such mode of connection can strengthen first piece of as large in customer charge easily burning out of table and show inlet wire control switch.Table inlet wire control switch burns out latter second piece, the 3rd piece table and will lose power supply and cause power failure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of secondary earth leakage protective coupling box, and solving Intelligent meter box does not have middle rank protection, enters to show line and service conductor loose contact, adds the problems such as area of having a power failure on a large scale when safeguarding; Be conducive to eliminating safe hidden trouble, increasing work efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of secondary earth leakage protective coupling box, comprise casing, described bottom half is provided with installing hole, its sidepiece is provided with through wires hole, described box house is provided with manifold type disconnecting link, intelligent leakage circuit breaker and connecting terminal block, described manifold type disconnecting link one end connects civil power, the other end is connected with connecting terminal block through intelligent leakage circuit breaker, described connecting terminal block is electrically connected with user's Intelligent meter box respectively through through wires hole, described casing is hingedly connected with case lid, described case lid is provided with can the window of drawing intelligent leakage circuit breaker switch.
Preferably, described casing adopts makrolon material, and described case lid is insulation transparent waterproof material.
Preferably, the overall orthogonal casing of described casing, the long 40cm of described casing, high 60cm, thick 15cm.
The beneficial effect that produces of technique scheme is adopted to be: the utility model effectively can reduce the labour intensity of workmen, support personnel's device security, contact well there will not be virtual connection, spark phenomenon.Set up obvious cut-off point, as long as the intelligent leakage circuit breaker pulled open inside secondary leakage guarantor coupling box and manifold type disconnecting link, effectively reduce power failure area.After adding the second class protection of Intelligent meter box, meet state's gateway in installing three grades of relevant regulations failed to report simultaneously.The utility model is convenient to install, transport, and economical and beautiful, increase work efficiency, reduce labour, design is simplified, and easy-operating feature, be applicable to batch production.Solve Intelligent meter box there is no middle rank protection, enter to show line and service conductor loose contact, add the problems such as area of having a power failure on a large scale when safeguarding; Be conducive to eliminating safe hidden trouble, increasing work efficiency.
