Abstract
The utility model relates to a kind of integrated form varistor, comprises piezo-resistance body, and the one side of described piezo-resistance body arranges unitary electrode; Another side arranges one or more electrode; In order to increase the fail safe of use, piezo-resistance body described in the utility model is provided with the electrode dockingundocking device respectively in the one side of one or more electrode.Employing the utility model can reduce the space required for protector, especially more obvious in three-phase power distribution system.
Description
Technical field
The utility model relates to a kind of varistor, especially a kind of for the integrated form varistor in surge protector.
Background technology
In various distribution system and electric equipment, varistor is a kind of most popular overvoltage protection element.And electric equipment or distribution system power generally have single-phase and three-phase point.Even single phase power supply also has phase line, zero line and ground wire.According to the piezo-resistance protection scheme used at present, minimum with 2 varistors (namely relatively with zero protecting over the ground).This considerably increases the space (such as surge protector just needs to save protection with L-PE and N-PE bis-) of protector.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of integrated form piezo-resistance, can reduce the space required for protector.
The utility model solves the technical scheme that its technical problem adopts: a kind of integrated form varistor, comprises piezo-resistance body, and the one side of described piezo-resistance body arranges unitary electrode; Another side arranges one or more electrode.
Further, in order to increase the fail safe of use, piezo-resistance body described in the utility model is provided with the electrode dockingundocking device respectively in the one side of one or more electrode.
The beneficial effects of the utility model are, solve the defect existed in background technology, can reduce the space required for protector, especially more obvious in three-phase power distribution system.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 (a)-(b) is the structural representation of an embodiment of the present utility model;
Fig. 2 (a)-(b) is the structural representation of another embodiment of the present utility model;
In figure: 1, body; 2, electrode.
Embodiment
With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of integrated form varistor as shown in Figure 1, be applied to single phase power supply system, comprise piezo-resistance body, the one side of piezo-resistance body arranges unitary electrode; Another side arranges two electrodes.In Fig. 1, shown in (a) figure is the front of varistor, shown in (b) figure or the back side of varistor.Disconnector can be installed separately if needed.
A kind of integrated form varistor as shown in Figure 2, be applied to three-phase power supply system, comprise piezo-resistance body, the one side of piezo-resistance body arranges unitary electrode; Another side arranges four electrodes.In Fig. 1, shown in (a) figure is the front of varistor, shown in (b) figure or the back side of varistor.Disconnector can be installed separately if needed.
The just embodiment of the present utility model described in above specification, various illustrating is not construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of utility model.
Claims (2)
