Normal operating conditions
"gPV"means a de fuse used for the fullrange of breaking capacity for the over current protection of solar photovollaic system.
Breaking Capacity:33kA Standard:GB/T 13539.6 IEC60269-6
This series of fuses is suitable for the rated dc vollage to 1500V, rated current to 32A line, and photovollaic panel and battery connected in sernes paralel, charging cornverter system to do short circuit break protection; At the same time, it protects photovoltaic power station, convergent inverter rectifier system and short circuit faull As well as the photovoltaic power goneration system surge current and short circuit fault overvoltage quick break prolection, rated breaking capacity to 20KA, the product in line with the intemational commission of electrical and industrial standards IEC60269 provisions.
Upper limit of ambient ar temperature does not exceed 90 ℃; Ambient air temperature is not lower than upper -50 ℃; The elevation of the instalationsite shall not exceed 2000m(if it exceeds 2000m, the requirements shall be noted, and the company can carry out design and development according to customer requirements).
The variable cross section mel made of pure silver sheet is encapsulated in the fuse tube made of high strength porcelain. The fuse tube is fled with chemicaly treated high purity quartz sand and specialy treated chemical materials as the arc extinguishing medium. The two ends of the melt are firmly connected with the contact by spot welkding.
CLBDF-32D 1A-32A 1500VDC Fuse Size:10×65mm Class of Operation gPV
Pull the fuse holkder(handle) at the fuse holder base with a little force directy from the base and put it into the fuse, as shown in FIG,4. Insert the fuse holder(handle) with the fuse hoider directly into the base, as shown in FlG.5.
Descniplion of advantages:(besides the advantages of using the fuse and base of pv 1000V, the following advantages are added)
1there are at least 6 places for ventilation and heat dissipalion, especially 5 and 6. The holow design in the middle quickly and effectively plays the heat dissipalion function. When multiple poles are combined, there is a 1mm heat dissipation channel between the two bases, which is more than 2 times higher than the previous heat dissipation channel of the clbdf-32d base.
2the screw anti-loosening function of clbdf-32d is used in igure A above. Meanwhile, the torque is stil higher than the national standard of 2.6Nm and can reach 3.0Nm.
3 when the operator installs and repairs the product, pull out the load fuse(handle). There is an insulating partition inside the base, which effectively prevents the operator from putting the handle into the base by mistake and causing the possibility of electric shock. The insulating partition moves as the load fuse(handle) is pulled out and inserted, as shown in the figure below.
4This product volume is smallthe capacity is big, breaks off the ability high, has the very big superiority compared with other company's product.
This product volume is smallthe capacity is big, breaks off the ability high, has the very big superiority compared with other company's product.
As shown in the figure above, our company USE 10x65, and some manufacturers use 14x51(or 10 85 of bussmann). Our fuse breaker has a smal diameter, which reduces the transverse length of the junction box. Compared with 10 85, our products reduce the longitudinal length, greatly reducing the volume of the junction box and the cost of the whole junction box.
The length of a product determines the value of high and low volage, under 14×51 orniginal ac 690 v for ordinary products, its do 1000v carrying capacity has reached the limit, let alone to the bearing of 1500v dc voltage, the longer the fusion tube, the ability of the load voltage is higher, the better the performance of arc extinction, the lower the risk factor, the 1500 v dc voltage arcing performance requires at least 12 fracture, at least 5 mm between each fracture spacing, then 12 fracture length at least 55 mm, plus to the ends of contact between the spacing, the length of the 14×51 is not enough, Can not effectvely play the role of arc extinguishing, its risk coefficient in the process of operation can be imagined.
