Description
Technical field
The utility model relates to technical field of electric appliances, particularly the current limiting pressure-limiting protector.
Background technology
The electric component of the current limliting of using in circuit is fuse, is connected in circuit, and the fuse when electric current is excessive in fuse will blow, and plays the effect of protection; Pressure limiting, prevent the thunderbolt electrical equipment be lightning arrester; be connected in parallel in circuit; when high voltage is arranged, thunder and lightning for example, lightning arrester will conductive earthing; separate a part of voltage; play the effect of protective device, in prior art, fuse and lightning arrester are respectively the structures of separating one; the shortcoming of have the trouble of installing, time-consumingly take a lot of work, connecting line is more will be installed respectively when mounted.
Summary of the invention
Technical problem to be solved in the utility model is exactly for above-mentioned shortcoming, provides a kind of installation to save labour, facilitate, connecting line is less, the one-mast support current limiting pressure-limiting protector of easy access.
Technical solution adopted in the utility model is; one-mast support current limiting pressure-limiting protector; comprise an insulator; there is mounting panel in the middle of insulator; there is upper connector above insulator; lower connector is below arranged; the fuse that clamping is arranged in the middle of upper connector and lower connector; it is characterized in that: described insulator is hollow core structures below middle part; the logical outside of hollow core structures upper side; be provided with lightning arrester in hollow core structures, the lead-in wire connection plate of lightning arrester upper end, the lead-in wire of lower end is drawn from hollow core portion.
Further say, described hollow core structures inner upper end is provided with Mume flower contact, and Mume flower contact and mounting panel are electrically connected to, and there is the structure that coordinates Mume flower contact the lightning arrester upper end.
Further say, lightning arrester lower end and insulator lower end are closed with unilateral locking device locking, and the lightning arrester contact has lock ring, and the ring arranged on locking device on a release draw ring and lightning arrester contact interlocks.
Further say, fuse is embedded in the middle of upper connector and lower connector
Further say, described locking device upper end is connected with rotary support, the locking device closure that the fusion tube lower end of fuse has rotary contact to make progress with the insulator upper end by rotary support, and when fuse failure, fusion tube Yin Lali disappears and automatically falls.
The beneficial effects of the utility model are: such one-mast support current limiting pressure-limiting protector has the pressure-limit current-limit effect simultaneously, also have advantages of install save labour, facilitate, connecting line is less, easy access; There is the structure that coordinates Mume flower contact the lightning arrester upper end, and the ring arranged on locking device on a release draw ring and lightning arrester contact interlocks, and fuse is embedded in the middle of upper connector and lower connector, has advantages of easy access.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one-mast support current limiting pressure-limiting protector.
Wherein: 1, insulator 2, mounting panel 3, upper connector 4, lower connector 5, fuse 6, lightning arrester 7, lock ring.
Embodiment
As shown in Figure 1; one-mast support current limiting pressure-limiting protector; comprise an insulator 1; there is mounting panel 2 in the middle of insulator; there is upper connector 3 above insulator; lower connector 4 is below arranged; the fuse 5 that clamping is arranged in the middle of upper connector and lower connector; it is characterized in that: described insulator is hollow core structures below middle part, and the logical outside of hollow core structures upper side, be provided with lightning arrester 6 in hollow core structures; the lead-in wire connection plate of lightning arrester upper end; the lead-in wire of lower end is drawn from hollow core portion, and the utility model had both had pressure limiting like this, has again the effect of current limliting.
Further say, described hollow core structures inner upper end is provided with Mume flower contact, and Mume flower contact and mounting panel are electrically connected to, and there is the structure that coordinates Mume flower contact the lightning arrester upper end, is easy for installation and maintenance like this.
Further say, lightning arrester lower end and insulator lower end are closed with unilateral locking device locking, and the lightning arrester contact has lock ring 7, and the ring arranged on locking device on a release draw ring and lightning arrester contact interlocks.
Further say, fuse is embedded in the middle of upper connector and lower connector
Further say, described locking device upper end is connected with rotary support, the locking device closure that the fusion tube lower end of fuse has rotary contact to make progress with the insulator upper end by rotary support, and when fuse failure, fusion tube Yin Lali disappears and automatically falls.
