Line box.
Background technology
Existing photovoltaic component terminal box inner lead is joined directly together with photovoltaic cell busbar, i.e., positive and negative polarity wire has always
Voltage is present.Both positive and negative polarity master-slave socket change when because positive and negative polarity wire without and terminal box in cell photovoltaic group string busbar it
Separated connection, therefore terminal still carries the open-circuit voltage of photovoltaic module, when people occurs for the joint imprudence for damaging insulation
Body contacts or there is potential safety hazard when being contacted with support.Its sub-assembly is rack-mount, some photovoltaic component terminal box
Wire and photovoltaic group string, which converge line, to be laid in support C-type steel groove, after photovoltaic group string converges line or damaged terminal box wire insulation
When occurring ground short circuit with metallic support, in photovoltaic group string（Equivalent to power supply）And earth point（Earth point tends not to look into easily
Find out）Between disconnected without switch and protection device, pin and box sub is extracted manually come disconnect can produce during earth-return circuit it is straight
Arc discharge is flowed, because the big arc discharge of electric current is very serious when irradiation level is preferable, because of direct current unlike exchange has zero passage arc extinguishing, to inspection
The personnel of repairing generate very big threat；If eliminating failure after earth point again by finding out, because earth point is indefinite in search procedure
Bigger potential safety hazard can more be caused by touching earth point unintentionally, and because the process time for searching earth point is longer, can
Can cause because of long-term ground connection it is on fire in inverter or remittance line poling, so as to expand fault coverage.When on fire in header box in addition,
Because of failure situation inside and out not clear header box, it is impossible to open header box shell easily, but in order to eliminate failure as early as possible, need to break
The connection of header box outside input and header box and inverter is opened, because outside remittance line and terminal box wire are substantially disconnected without that can produce
The device prescribed, directly unpluging male and female head also can be because arcing produces danger.
