Abstract
The utility model relates to an alarm fuse of BRD series, composed of an outer shell, a contact socket, a plug core, etc., wherein, the plug core can be conveniently inserted in the socket or be split out from the socket. The utility model is applicable for a control circuit which is provided with direct current rated voltage of 220V and below, and rated current of 10 A and below, and for indoor appliances of a signal circuit. The utility model can be used for shortcircuit or overload protecting.
Description
The present invention relates to generating, power transformation, distribution electric component, relate in particular to a kind of warning fuse.
At present, Chang Yong R
X1-10 type fuse is single fusion tube, and terrain falls the board indication, the output contact concentrated alarm, and changing fuse needs with spare fuse welding, easy misoperation in service.Because this product has only a kind of model, be to protrude the screen back to install.In use, install dumbly, kind is single, and expense is higher, after fault takes place, is difficult in time finding.
The objective of the invention is to overcome the defective of prior art, provide a kind of and can overcome misoperation, can after melt fusing, can send sound and light, can give other signal circuits by output contact again, the discovery fault point is fast, and system adopts approved product because of fusion tube, and it is fast to change fusion tube, and volume is little, series of products handsome in appearance.
According to BRD series warning fuse of the present invention, it is made up of shell, contact socket, slotting stamen etc., fusion tube intermediate plate and conduction screw are installed on the base plate in the described shell, on the described slotting stamen fusion tube, relay, resistance, electric whistle, indicator light are installed, its slotting stamen can insert described socket easily or extract from socket.
According to BRD of the present invention series warning fuse, in adorn two fusion tubes.These series of products have three kinds of models, can embed installation and also can protrude installation.
Below in conjunction with drawings and Examples BRD series alarm of the present invention is described in further detail.
Fig. 1 is the structural representation of BRD series alarm of the present invention.
Fig. 2 is the electrical schematic diagram of the BRD-1 type of BRD series alarm of the present invention.
Fig. 3 is the electrical schematic diagram of the BRD-2 type of BRD series alarm of the present invention.
Fig. 4 is the electrical schematic diagram of the BRD-3 type of BRD series alarm of the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, BRD series warning fuse of the present invention is made up of shell 1, contact socket 2, slotting stamen 3 etc.Fusion tube intermediate plate 4 and conduction screw 5 wherein are installed on the base plate in the shell 1, installation fusion tube 6, relay 7, resistance 8, electric whistle 9, indicator light 10, slotting stamen 3 can insert or extract contact accessory power outlet 2 by contact output plug 11 easily on the slotting stamen 3, fusion tube 6 is stuck on the intermediate plate 4, electric component in the shell 1 is connected with printed panel 12 circuit, translucent cover 13 is arranged at shell 1 top, and product nameplate frame 14 and nameplate 15 are arranged in the translucent cover 13.
During use, relay 7 (ZJ) is connected to fuse load side (3 and 4 terminal), electric whistle 9 (FM) is connected with beacon lamp 10 (XD) after fuse mains side (1 and 2 terminal) is received in relay 7 (2J) normal open contact.During normal the operation, the charged adhesive of relay 7 (ZJ), the normal open contact disconnects, and fuse does not signal, when short circuit or overload, the interior melt fusing of fusion tube 6 (1RD or 2RD), relay 7 (ZJ) does not have electricity and discharges.At this moment, normal open contacting electric whistle 9 (FM) and indicator light 10 (XD) are sounded and light signal, and normal open contacting 5 and 6 terminals can be related with other control circuits.The operations staff can in time fix a breakdown, and the support equipment safe operation can be extracted easily and insert stamen 3 replacing fusion tubes 6 (1RD or 2RD) simultaneously.
Fusion tube 6 used in the present invention is approved products, and fusion tube is a porcelain tube, filling quartz sand and melt in the fusion tube, porcelain tube two ends lock ring steel cap.
BRD series warning fuse of the present invention can embed installation and also can protrude installation.These series of products have three kinds of models, should select for use as the case may be in the use.
Claims (3)
1, a kind of warning fuse, form by shell, contact socket, lock pin etc., it is characterized in that: fusion tube intermediate plate and conduction screw are installed on the base plate in its shell, fusion tube, relay, resistance, electric whistle, indicator light are installed on the lock pin, its lock pin can insert socket easily or extract from socket.
2, warning fuse according to claim 1, it is characterized in that: relay is connected to the fuse load side, and electric whistle is connected with indicator light after the fuse mains side is received in relay normal open contact.
