Abstract
The invention discloses a fuse protection cover which comprises a protection cover body and connecting pieces. The protection cover body is connected with an upper contact seat carrying a fuse through the connecting pieces. A temperature sensor is arranged in the protection cover body. An alarm is arranged outside the protection cover body. The insulating protection cover body is adopted to protect exposed parts of a contact, and is extremely convenient to install; moreover, the temperature sensor and the alarm can be additionally arranged and the temperature sensor can trigger the alarm to give an alarm when the contact point of the fuse becomes loose in the running process or the contact resistance of the fuse increases due to long-time running to cause heat generation so that running checking personnel can timely find the condition in the checking process. Therefore, unnecessary accidents are greatly reduced, and the technical problem that in the prior art, one phase of the fuse is grounded to cause an accident is effectively solved.
Description
Technical field
The invention belongs to controller switching equipment and safeguard accessory technical field, be specifically related to a kind of fuse protection cover.
Background technology
Fuse is that a kind of structure is simple, simple operation, One's name is legion distribution protection equipment, find in operation work statistic in recent years, the fault of fuse happens occasionally, and wherein has normal operating of protection, also has abnormal obstacle to occur.And the fault of fuse mainly burns out cause by carrying the upper contact head of melt, because existing fuse volume inlet wire contact place has part metals in atmosphere exposed, and the setting height(from bottom) of fuse is not high, installation is rear and metal cross arm is angled, easily fall into because of branch and child plays time metal object be thrown into and cause single-phase earthing accident, affect the safe operation of circuit.Therefore, as long as can effectively address this problem, just greatly can reduce the failure rate of fuse, improve the reliability of power supply.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of fuse protection cover, and adopt the protective cover body of insulation, the position exposed to contact place is protected, and it is extremely convenient to install, and installation personnel just can complete installation in 1 ~ 2 minute; Temperature inductor and alarm can also be added, the fuse contact resistance increase that fuse operationally a little loosens as come in contact or the time is excessively of a specified duration causes heating, temperature inductor passes through thermoinduction, triggered alarm is reported to the police, rolling inspection personnel can Timeliness coverage when checking, greatly reduce unnecessary accident to occur, efficiently solve the technical problem that in prior art, fuse single-phase earthing accident occurs.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of fuse protection cover, comprises protective cover body and connector, and described protective cover body is connected with touch base on year melt by connector.The position exposed to contact place is protected, and installation is extremely convenient.
Preferably, described protective cover body is the catch of insulation, and protective cover body outer surface is circular arc, and described connector one end connects protective cover body internal surface, and the connector other end connects touch base on year melt.
Preferably, described connector and carry angle melt being formed 30 ~ 60 ° between touch base.Have certain angle with horizontal direction when fuse is installed, connector and carry angle melt being formed 30 ~ 60 ° between touch base, then, after installation, protective cover body can remain on the position of basic horizontal.
Preferably, described protective cover body is the cover body of insulation, and protective cover body lower limb is connected to by connector and carries on melt on touch base.
Preferably, described protective cover body left and right edges is closed up by connector.Position exposed for contact place is all wrapped up, safety and reliability, can also dustproof effect be played.
Preferably, described connector is fire-retardant nylon clasp nail.Easy for installation, and flame-resistant insulation, safer.
Preferably, the material of described protective cover body is silicon rubber.Excellent insulation performance, and fuse is not damaged, safe and reliable.
Preferably, be provided with temperature inductor inside described protective cover body, outside protective cover body, be provided with alarm.The fuse contact resistance increase that fuse operationally a little loosens as come in contact or the time is excessively of a specified duration causes heating, temperature inductor passes through thermoinduction, triggered alarm is reported to the police, and rolling inspection personnel can Timeliness coverage when checking, greatly reduces unnecessary accident and occurs.
The invention discloses a kind of fuse protection cover, adopt the protective cover body of insulation, the position exposed to contact place is protected, and it is extremely convenient to install; Temperature inductor and alarm can also be added, the fuse contact resistance increase that fuse operationally a little loosens as come in contact or the time is excessively of a specified duration causes heating, temperature inductor passes through thermoinduction, triggered alarm is reported to the police, rolling inspection personnel can Timeliness coverage when checking, greatly reduce unnecessary accident to occur, efficiently solve the technical problem because of branch or Bird's Nest and metallic conduction location contacts or the play single-phase earthing that may cause or line to line fault accident because of child of fuse in prior art.
