Abstract
The utility model relates to a capacitor with a combined discharge resistor, wherein a combined discharge resistor is arranged on a capacitor. The combined discharge resistor comprises resistor elements, a discharge resistor housing and a terminal. The resistor elements are connected according to a predetermined manner and then are placed in the discharge resistor housing. The lower end of the discharge resistor housing is provided with the terminal. The resistor elements are connected with the terminal. According to the technical scheme of the utility model, the capacitor with the combined discharge resistor can be prepared into any shape according to actual needs. When needed, the discharge resistor can be directly inserted into the capacitor to be used. When not needed, the discharge capacitor can be pulled out of the capacitor. Therefore, the capacitor with the combined discharge resistor is convenient to use and excellent in electric connection reliability. The quality defects during the welding process in the prior art can also be eliminated. When the combined discharge resistor is damaged, the combined discharge resistor can be directly pulled out and replaced with a new one. In this way, the combined discharge resistor is low in usage and maintenance cost. Since the combined discharge resistor is arranged outside the capacitor, the combined discharge resistor has no influence on the temperature rise of the capacitor. The service life of the capacitor is therefore prolonged. Therefore, the usage requirements during the application process can be met.
Description
Technical field
The utility model relates to a kind of capacitor, relates in particular to a kind of capacitor with combined type discharging resistance.
Background technology
The storage electric charge that electric capacity is approaching by two and electrode that conductor mutually insulated is made forms and the device of electric energy.We know, capacitor is store electrical energy, in circuit, uses very extensively.But in some occasion, during such as equipment such as maintenance capacitor box etc., the energy of capacitor stores damage to equipment or the person, so energy must be bled off to just safety.In fact, the discharge principle of capacitor is very simple, be exactly with resistance by the electric capacity short circuit, bleed off the residual charge in capacitor by resistance.Such resistance is exactly discharge resistance.The parameters such as the size of discharge resistance resistance, power, comprehensively choose according to capacitance, circuit voltage and the permission of the reality in circuit discharge time.
The discharge resistance of existing capacitor, comprise a plurality of resistive elements, and these resistive elements are by parallel or be connected in circuit.Normally by the elongated leads pin of resistive element welding place in circuit.Such welding manner, the one, to waste time and energy, resistive element is more, and weld time is longer; The 2nd, the quality problems such as rosin joint easily appear during welding.Therefore, existing capacitor discharge resistance can not meet actual operation requirements.
The utility model content
The deficiency that the utility model exists for prior art just, provide a kind of capacitor with combined type discharging resistance.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of capacitor with combined type discharging resistance, combined type discharging resistance is installed on described capacitor, combined type discharging resistance comprises: resistive element, discharge resistance housing and terminals, resistive element is according to after being scheduled to connection, be arranged in the discharge resistance housing, lower end at the discharge resistance housing is provided with terminals, and resistive element and terminals link together.
As improvement of the technical scheme, the oral area bottom of described terminals is provided with the targeting port with tapering, is provided with fluting on targeting port.
As improvement of the technical scheme, described capacitor comprises: housing cylindraceous, and the top oral area of housing is provided with lid, and housing and lid form airtight space; At the arranged outside binding post of lid, binding post is through lid; Be provided with capacity cell in enclosure interior, capacity cell and binding post link together.
As improvement of the technical scheme, described binding post inserts in terminals, and binding post and terminals interference fit.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Capacitor with combined type discharging resistance described in the utility model, combined type discharging resistance can be made shape arbitrarily according to actual needs, when needs are used, directly discharge resistance is inserted on capacitor and uses and get final product, when not needing, can pull out, so not only easy to use, and the reliability of electrical connection of discharge resistance that utilized interference fit to guarantee, eliminated the quality problems of existing welding procedure.When combined type discharging resistance damages, directly pull out replacing and get final product, easy to use, the operation and maintenance cost is low, and it is arranged on the capacitor outside, any impact can not arranged on the temperature rise of capacitor, has extended capacitor useful life, meets actual operation requirements.
