Abstract
The utility model relates to an electric lightning proof two-way switch, which is suitable to be installed on various power supply lines. The utility model is characterized in that the switch is composed of an insulating bakelite casing, a ceramic insulating base and eight binding posts installed on the base (two of which are lightning proof ground protection binding posts) and two two-way blade. The two lightning proof ground protection binding posts are connected in series through wires with good conduction performance, one end of the two binding posts are connected with the ground protection wire of an electric appliance, and the other ends are effectively grounded. At normal times, normal power supply is realized by pushing the blades upward to connect the blades with the binding posts of a power line, and normal power cut can be realized by pulling the blades downward to separate the blades from the binding posts of the power line; in thundershower weathers with strong convection, by pulling down the blades to connect the blades with the lightning proof ground protection binding posts, thunderbolt conducted along the power supply line can be avoided from being release indoor, causing electric appliance damage and (or) casualty of people. The electric lightning proof two-way switch has the advantages of simple structure and reliable performance.
Description
Technical field:
The utility model relates to the two-way electric switch of a kind of lightning protection.When being applicable to normal power supply in the various supply lines for have a power failure and take place thunderstorm hour to electrical equipment and (or) personnel's protection.
Background technology:
Existing product is by the bakelite shell, and porcelain insulator foot and six binding posts and two unidirectional plug-in strip blades of being installed on the base are formed.Be widely used in the various supply lines, have for power failure function and excess load defencive function.Its shortcoming be when disconnecting, still can not effectively avoid along discharge in the thunder and lightning inlet chamber of supply line's conduction damage electrical equipment and (or) cause people's injures and deaths.
Summary of the invention:
The purpose of this utility model provides a kind of lightning protection bidirectional switch that is widely used in the various supply lines.
The purpose of this utility model is achieved through the following technical solutions: a kind of lightning protection bidirectional switch; it is characterized in that the bakelite shell, porcelain insulator foot and eight binding posts (wherein have two and be lightning protection protection binding post) and two two-way plug-in strip blades of being installed on the base are formed.
The beneficial effects of the utility model:
Because this lightning protection bidirectional switch has designed two lightning protection protection binding posts; and implement lightning protection and protect connection; plug-in strip can two-wayly connect; when meeting strong convection thunderstorm weather; switchblade knife is broken away from the supply lines binding post; drop-downly be connected with two lightning protections protection binding posts; promptly realize the whole ground connection of all indoor gauzes this moment; in when, thunder and lightning taking place and being added in the supply line when; the air that two binding posts of supply lines are fixedlyed connected with plug-in strip between the termination terminal will be punctured by thunder and lightning; form path; cause all indoor gauzes all to be with thunder and lightning; this moment is owing to there is a ground protection, and thunder and lightning will be gone into ground along thunder proof protection ground line moment, thus avoid thunder and lightning indoor release damage electrical equipment with (or) cause people's injures and deaths.
When this lightning protection bidirectional switch is in the normal power supply state; in when, thunder and lightning taking place suddenly and being added in the supply line; minimum resistance between very important person and supply line's point of discharge such as the jack etc. is during greater than the resistance between this lightning protection bidirectional switch electrical appliance binding post and the lightning protection protection binding post; thunder and lightning will be preferably gone into ground along thunder proof protection ground line moment, causes people's injures and deaths thereby also can avoid or alleviate thunder and lightning in indoor release.
Description of drawings:
Fig. 1: the internal structure of lightning protection bidirectional switch and connection diagram
Among the figure: 1 and 2 is the power line binding post, and 3 and 4 is plug-in strip stiff end binding post, also is simultaneously excess load protection fuse binding post, and 5 and 6 is the electrical appliance binding post; 7 and 8 for lightning protection protection binding post, also is electrical equipment ground protection line binding post simultaneously.9 and 10 are respectively the live wire and the zero line of power line; 11 and 12 are respectively disjunct two plug-in strip blades; 13 and 14 are respectively two excess load protection fuses, and 15 and 16 is the electrical appliance connecting line, and 17 is electrical equipment ground protection line; 18 is the thunder proof protection ground line; 17 realize being communicated with (can connect with single line) when reality is connected by polyphone lightning protection binding post 7 and 8 with 18, and 19 is the porcelain base, and 20 is electrical appliance; 21 is the electrical appliance shell, and 22 is the earth.
Embodiment:
Preferred version of the present utility model is to adopt eight binding posts (wherein have two and be lightning protection protection binding post), bidirectional switch design.Connection mode is: power line binding post (1) and (2) are connected the live wire (9) and the zero line (10) of power line respectively, realize normal power supply when pushing away on switchblade knife (11) and (12) when closing up with it, realize the outage safeguard protection during disconnection; Plug-in strip stiff end binding post (3) is connected two excess load protection fuses (13) and (14) respectively simultaneously with (4); Electrical appliance binding post (5) links to each other with (14) with two excess load protection fuses (13) respectively with (6) top, and the below is connected electrical appliance (20) by electrical appliance connecting line (15) with (16); Lightning protection protection binding post (7) and (8) is contacted with the lead with excellent conductive performance; one end is realized the electrical leakage ground protection by ground protection line (17) the connecting circuit shell (21) of electrical equipment; the other end connects the earth (22) by thunder proof protection ground line (18), when switchblade knife (11) with (12) are drop-down realizes lightning protection protection when closing up with it.The utility model has increased the lightning protection defencive function on the basis of saving the existing product repertoire from damage.
Operation principle:, promptly realize normal electricity consumption with pushing away (this moment, switchblade knife disconnected with the two lightning protections protection binding post of setting up) when being connected with two binding posts of supply lines respectively on the switchblade knife; When meeting strong convection thunderstorm weather; switchblade knife is broken away from the supply lines binding post; drop-downly be connected with two lightning protections set up protection binding post; promptly realize the whole ground connection of all indoor gauzes this moment; in when, thunder and lightning taking place and being added in the supply line when; two binding posts of supply lines and the air between the plug-in strip stiff end binding post will be punctured by thunder and lightning; form path; cause all indoor gauzes all to be with thunder and lightning; this moment is owing to there is ground protection; thunder and lightning will be gone into ground along thunder proof protection ground line moment, thus avoid thunder and lightning indoor release damage electrical equipment and (or) cause people's injures and deaths.
