Abstract
The utility model belongs to the capacitor field, and specifically relates to a three-terminal cylindrical capacitor with a grounding pole. The three-terminal cylindrical capacitor comprises terminals, a housing and a top cover, the top cover is positioned at an upper end of the housing, and the two terminals are installed on the top cover. The three-terminal cylindrical capacitor is characterized in that the top cover is also provided with the grounding pole welded on the top cover. The three-terminal cylindrical capacitor has the advantages that grounding effect is good, and the three-terminal cylindrical capacitor can be used safely and inspected conveniently. The three-terminal cylindrical capacitor is not influenced by installation environment, housing electric leakage is prevented, good grounding effect can be achieved, and inspection can be carried out conveniently.
Description
Technical field
The utility model belongs to capacitor area, is specifically related to a kind of three terminal cylindrical condensers of post with ground.
Background technology
The key factor that capacitor need to be considered in the time putting installation into operation is exactly ground connection.Existing cylindrical condenser earthing mode is the bolt ground connection carrying by aluminum casing bottom, reliable in theory by this earthing mode of bolt ground connection, but environment is severe at the scene, dust is many time, contact in other words local when remaining other megohmite insulants with bolt, often likely cause bolt can not effectively be grounded function, also more difficult when inspection personnel checks, at this time if there is body leakage, likely injure personal safety.
Utility model content
The purpose of this utility model is that the earth stud that solves prior art cylindrical capacitor is arranged on aluminum casing bottom, affected by environment for use, easily there is body leakage, jeopardize the defect of personal safety, provide a kind of earthing rod to be arranged on aluminum hull top, affected by environment for use little, can not leak electricity, use three terminal cylindrical condensers of safety.
The utility model is achieved by the following technical solution:
Be a kind of three terminal cylindrical condensers, comprise terminal, housing and top cover, top cover is positioned at the upper end of housing, and two terminals are arranged on top cover, it is characterized in that being also provided with 1 earthing rod on top cover, and described earthing rod is welded on top cover.
As a preferred version of the present utility model: earthing rod is welded on the dipping hole of top cover upper end, insert in dipping hole earthing rod lower end.
As a preferred version of the present utility model: the bottom of housing is provided with earth stud.
Principle of the present utility model is as follows:
Top cover, before assembling, is evenly coated in and floods around hole, within being less than 8 millimeters of scopes with aluminium weldering scaling powder.Capacitor, after vacuum impregnation operation, seals dipping hole without scolding tin, but places earthing rod in dipping hole, then welds solid with scolding tin.Capacitor puts into operation while installation, can directly be grounded function with wire through earthing rod, also can be used as auxiliary earthing mode, has so just greatly improved the safe coefficient in capacitor running.Even if site environment complexity, earthing effect is also substantially unaffected, no matter be that patrol officer checks or maintenance personal fixes a breakdown more convenient.
The utlity model has the advantage that earthing effect is good, use safely, be convenient to inspection.The utility model is not subject to the impact of installation environment, there will not be body leakage, can realize good earth effect, and is convenient to check.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
As shown in FIG.: 1. terminal; 2. earthing rod; 3. top cover; 4. housing; 5. earth stud.
Embodiment
As shown in Figure 1 and Figure 2, housing 4 upper ends of cylindrical condenser are provided with top cover 3, and top cover 3 is provided with 1 and 1 earthing rod 3 of two terminals, and the bottom of housing 4 is also provided with an earth stud 5.
When the utility model is made: top cover 3, before assembling, is evenly coated in and floods hole (dipping hole is that the art personnel know, not shown in FIG.) around with aluminium weldering scaling powder, within being less than 8 millimeters of scopes.Capacitor, after vacuum impregnation operation, seals dipping hole without scolding tin, but places earthing rod 2 in dipping hole, then welds solid with scolding tin.
When the utility model uses, realize auxiliary earth function with wire through earthing rod 2, coordinate original earth stud 5, greatly improved the safe coefficient in capacitor running.Even if site environment complexity, earthing effect is also substantially unaffected, no matter be that patrol officer checks or maintenance personal fixes a breakdown more convenient.
The present embodiment is not limited to above embodiment, as can also be do not used earth stud, only adopts earthing rod to be grounded function.
Claims (3)
1. three terminal cylindrical condensers, comprise terminal, housing and top cover, and top cover is positioned at the upper end of housing, and two terminals are arranged on top cover, it is characterized in that being also provided with 1 earthing rod on top cover, and described earthing rod is welded on top cover.
2. three terminal cylindrical condensers according to claim 1, is characterized in that earthing rod is welded on the dipping hole of top cover upper end, and insert in dipping hole earthing rod lower end.
